Problem: ScreenLines may not be correctly initialized, causing hang
(Olaf Seibert, after 9.0.0220)
Solution: always initialize ScreneLines when allocating a screen
(Olaf Seibert)
ScreenLines and related structures could be left uninitialized
causing a screen update to run into an infinite loop when using latin1
encoding.
Partly caused because by patch 9.0.0220, which makes mb_ptr2len return
zero for NUL

Problem: Cannot use terminal alternate fonts (PMunch)
Solution: Support terminal alternate fonts using
CSI SGR 10-20 and t_CF code (PMunch)
Add support for alternate font highlighting
This adds support for alternate font highlighting using CSI SGR 10-20.
Few terminals currently support this, but with added tool support this
should improve over time. The change here is more or less taken from how
colors are configured and applied, but there might be some parts I
missed while implementing it. Changing fonts is done through the new
`:hi ctermfont` attribute which takes a number, 0 is the normal font, and
the numbers 1-9 select an "alternative" font. Which fonts are in use is
up to the terminal.

Problem: Unused assignments when checking the value of 'listchars'.
Solution: Loop only once when just checking the value. Add a test to
check that this change doesn't cause double-free.

Problem: statusline may look different than expected
Solution: do not check for highlighting of stl and stlnc characters
statusline fillchar may be different than expected
If the highlighting group for the statusline for the current window
|hl-StatusLine| or the non-current window |hl-StatusLineNC| are cleared
(or do not differ from each other), than Vim will use the hard-coded
fallback values '^' (for the non-current windows) or '=' (for the
current window). I believe this was done, to make sure the statusline
will always be visible and be distinguishable from the rest of the
window.
However, this may be unexpected, if a user explicitly defined those
fillchar characters just to notice that those values are then not used
by Vim.
So, let's assume users know what they are doing and just always return
the configured stl and stlnc values. And if they want the statusline to
be non-distinguishable from the rest of the window space, so be it. It
is their responsibility and Vim shall not know better what to use.

Problem: cannot complete option values
Solution: Add completion functions for several options
Add cmdline tab-completion for setting string options
Add tab-completion for setting string options on the cmdline using
`:set=` (along with `:set+=` and `:set-=`).
The existing tab completion for setting options currently only works
when nothing is typed yet, and it only fills in with the existing value,
e.g. when the user does `:set diffopt=<Tab>` it will be completed to
`set diffopt=internal,filler,closeoff` and nothing else. This isn't too
useful as a user usually wants auto-complete to suggest all the possible
values, such as 'iblank', or 'algorithm:patience'.
For set= and set+=, this adds a new optional callback function for each
option that can be invoked when doing completion. This allows for each
option to have control over how completion works. For example, in
'diffopt', it will suggest the default enumeration, but if `algorithm:`
is selected, it will further suggest different algorithm types like
'meyers' and 'patience'. When using set=, the existing option value will
be filled in as the first choice to preserve the existing behavior. When
using set+= this won't happen as it doesn't make sense.
For flag list options (e.g. 'mouse' and 'guioptions'), completion will
take into account existing typed values (and in the case of set+=, the
existing option value) to make sure it doesn't suggest duplicates.
For set-=, there is a new `ExpandSettingSubtract` function which will
handle flag list and comma-separated options smartly, by only suggesting
values that currently exist in the option.
Note that Vim has some existing code that adds special handling for
'filetype', 'syntax', and misc dir options like 'backupdir'. This change
preserves them as they already work, instead of converting to the new
callback API for each option.

Problem: incorrect heights in win_size_restore()
Solution: avoid restoring incorrect heights in win_size_restore()
Changing 'showtabline' or 'cmdheight' in the cmdwin restores incorrect
window heights after closing the cmdwin.
This may produce a gap between the cmdline and the window above.
Solution: restore window sizes only if the number of lines available for windows
changed; subtract the rows of the tabline, cmdline and last window's statusline
from 'lines' (other statuslines don't matter).

Problem: screenchar(), screenchars() and screenstring() do not work
properly when 'encoding' is set to a double-byte encoding.
Solution: Fix the way the bytes of the characters are obtained.

Problem: Ruler not drawn correctly when using 'rulerformat'.
Solution: Adjust formatting depending on whether the ruler is drawn in the

Problem: Function for setting options not used consistently.
Solution: Use a function for 'encoding' and terminal options. (Yegappan

Problem: Still some "else if" constructs for setting options.
Solution: Add a few more functions for handling options. (Yegappan
