Problem: Libvterm can't handle a long OSC string that is split.
Solution: When an incomplete OSC string is received copy it to the parser
buffer. Increase the size of the parser buffer to be able to
handle longer strings.
Problem: Compiler warning for visibility attribute not supported on MinGW
builds.
Solution: Don't add the attribute when we don't expect it to work.
(Christian Brabandt)
Problem: Cannot select text in a terminal with the mouse.
Solution: When a job in a terminal is not consuming mouse events, use them
for modeless selection. Also stop Insert mode when clicking in a
terminal window.
Problem: Libvterm doesn't handle illegal byte sequence correctly.
Solution: After the invalid code check if there is space to store another
character. Allocate one more character. (zhykzhykzhyk, closes
#2614, closes#2613)
Problem: Terminal window colors wrong when using Terminal highlighting.
Solution: Set ansi_index when setting the default color. Also cache the
color index for Terminal. (Ozaki Kiichi, closes#2393)
Problem: Libvterm ANSI colors can not always be recognized from the RGB
values. The default color is wrong when t_RB is empty.
Solution: Add the ANSI color index to VTermColor.
Problem: Libvterm has its own idea of character width.
Solution: Use the Vim functions for character width and composing to avoid a
mismatch. (idea by Yasuhiro Matsumoto)
Problem: The cursor shape is wrong after switch back from an alternate
screen in a terminal window. (arius Gedminas)
Solution: Change bitfield to unsigned. Set flag that cursor shape was set.
Problem: Can't use the alternate screen in a terminal window.
Solution: Initialze the alternate screen. (Yasuhiro Matsumoto, closes
#1957) Add term_getaltscreen().
Problem: Build problems with terminal on MS-Windows using MSVC.
Solution: Remove stdbool.h dependency. Only use ScreenLinesUC when it was
allocated. Fix typos. (Ken Takata)
Problem: No terminal emulator support. Cannot properly run commands in the
GUI. Cannot run a job interactively with an ssh connection.
Solution: Very early implementation of the :terminal command. Includes
libvterm converted to ANSI C. Many parts still missing.
