Instead of having the user tell how many days to load, calcurse can
calculate an overestimation from the running configuration (panel size,
appearance of headers and separators etc.)
The configuration variable conf.multiple_days is turned into a Boolean
that switches the feature on and off.

The number of days displayed in the APP panel has been made
configurable, maximum 21 days, default seven days.
With several days in the APP panel, it may be desirable to "squeeze" the
entries by leaving out the final empty line of each appointment and
lower the number of lines between consecutive days (0, 1, or 2). Both
are made general configuration options. To make a uniform display, an
empty line is added to a day without appointments, if appointments have
an empty line.

Much in the calendar is based on the selected day, struct date
slctd_day, in ui-calendar.c.
On the screen it is highlighted with a deviating colour. The highlight
effect has been changed to a pair of red square brackets that do not
obscure the day colour.
The week number (in the frame) used to be that of the selected day, but
has no obvious relation to the days in the APP panel. It has been
replaced by the year day number of the selected day. The week numbers of
all visible weeks are displayed to the left of the calendar.
Dates are displayed also for the overlapping parts of the first and last
week of the month (which do not belong to the month).
Days are accessible in the appointments panel as well as in the
calendar. Hence, validation of days (= inside UNIX time limits) must be
extended from the calendar (in ui_calendar_move()) to include loaded
days (in day_store_items()).

A scroll window consists of a pad to write on, and a window through
which to view the pad, the viewport. The pad may change in size when new
contents are loaded into the scroll window. If so, the pad size is set
with wins_scrollwin_set_linecount(). But the offset into the pad (the
top line to be displayed in the viewport) is not adjusted, although it
may not be appropriate for the new pad size. The same is the case when a
scroll window is resized and the viewport changes size. This is probably
the cause of the problem solved by commit 0b46ad4, Avoid blank space
after the last list box item, and the fix has been removed.
The wins_scrollwin_set_linecount() has been renamed
wins_scrollwin_set_pad() and sets size as well as offset. The offset is
only changed if necessary.

The configuration settings for calendar view (monthly/weekly) and todo
view (hide/show completed) used to be saved automatically on calcurse
exit, with values taken from the current interactive settings. They
could not be set explicitly in the configuration menues. Configuration
settings are no longer saved on program exit, but on exit from the
configuration menu. This means that the saved values are those that were
current when the configuration menu was entered. To change a saved
value, you must set the view as desired and then enter/exit the
configuration menu.
The preferred calendar and todo views are no longer automatically taken
from the interactive settings, but are explicitly set in the general
options menu. Default values are monthly view and hide completed view.

A reload action will do nothing if in-memory data as well as data files are
unchanged. This commit accomplishes the equivalent for a save action.
Because saving of configuration data and key bindings are mixed up with saving
of data files, any changes in those will only be saved if data files also have
changed. Hence, configuration data and key bindings are also saved upon exit
from the configuration menu.

Internally characters (keys) have two representations: integers and key
names. Key names are characters strings, usually the name of the
character; e.g., the character A has the representations 65 and "A", and
the tab character the representations 9 and "TAB".
The function keys_int2str() turns the integer representation of a
key/character into the key name.
For display purposes the key names are usually confined to have display
width at most three. Some curses pseudo-keys have longer key names;
e.g., the back-tab character is "KEY_BTAB". A long key name makes a
character difficult to recognize in the status bar menu.
The key name of a multibyte, UTF-8 encoded character is the conventional
Unicode name of the code point; e.g., the character ü has key name
"U+00FC" because ü is the code point 0xFC. Most of these look alike in
the status bar menu.
The patch makes the key name of a multibyte character look like that of
a singlebyte character: the character itself, i.e. the key name of the
character ü is "ü".
The main tool is implementation of a utf8_encode() routine.

When a scrollbar is on display in APP or TOD windows, the right
vertical border (outside the scrollbar) is not highlighted
when the window is selected.
The scrollbar is always highlighted:
- when APP or TOD is deselected
- in configuration windows where borders otherwise are not
The patch moves the scrollbar parameters (except highlight)
from arguments of draw_scrollbar() to the function itself.
The highlight argument was 1; instead it is set higher in
the call hierarchy (wins_update_panels()) and passed on down.

Commit f8e6e0d (Fix no-colour theme, 2017-12-10) partly destroyed the
cursor in getstring() by turning it into a solid block. The fix
reintroduces wchgat() which requires a color pair argument. When no
colors are wanted, color pair 0 is used.
A similar problem exists in the layout and colour customization windows
and is fixed in the same way: move to the position and apply the reverse

In the default colour setup (white on black), white could only
with great difficulty be used as customized foreground colour,
because the colour pair COLR_CUSTOM then was identical to
COLR_DEFAULT (default on default). This made it impossible to
distinguish the selected element in lists.
The patch turns on the video attribute bold when default is chosen
as foreground colour.

Code point mapping adjusted for multibyte characters to avoid the
ncurses range 0-KEY_MAX.
This includes three fixes:
1) test sequence in keys_assign_binding(),
2) reassemble multi-byte character in keys_wgetch(),
3) check for already in use in keys_assign_binding().
Rearrangement of code. The introduction of allocated memory in
keys_int2str() has as a consequence that check for recognized ncurses
pseudo characters now are in two places: keys_str2int() and
custom_keys_config(). The latter was moved from keys_wgetch() to improve
user information.
More informative warning messages in custom_keys_config().

A new function keys_wgetch() reads full UTF-8 characters instead of
single ASCII characters only.
Key bindings for regular ASCII characters are stored in a hash map while
the actions of keys with higher code points are stored in a linked list
for space efficiency.
The key serialization methods are updated to handle UTF-8 characters as
well; extended UTF-8 characters (characters not in the ASCII range) are
serialized by using the hexadecimal representation of the corresponding
code points (e.g. "U+00E4").

The pair_content() function can be used to retrieve a color pair. The
foreground and the background color numbers are written to addresses
specified by the second and third parameters. While both parameters were
optional in older ncurses implementations (making it possible to pass
NULL pointers if the one does not care about either foreground or
background color), recent implementations seem to assume that both
parameters are valid pointers. Thus, instead of passing NULL, we need to
pass a pointer to a dummy variable when we do not care about the
background color.
