Problem: Terminal debugger only works with the terminal feature.
Solution: Make it also work with a prompt buffer. Makes it possible to use
on MS-Windows. Various other improvements. (closes#3012)
Problem: Terminal debugger doesn't handle command arguments.
Solution: Add the :TermdebugCommand command. Use a ! to execute right away.
(Christian Brabandt)
Problem: Terminal debugger doesn't handle arguments.
Solution: Use <f-args> and pass all the arguments to gdb, e.g. the core file
or process number. (suggested by Christian Brabandt) Disallow
starting the debugger twice.
Problem: Terminal debugger: can't re-open source code window.
Solution: Add the :Source command. Also create the window if needed when
gdb stops at a source line.
Problem: Terminal balloon only shows one line.
Solution: Split into several lines in a clever way. Add balloon_split().
Make balloon_show() accept a list in the terminal.
Problem: Cannot use 'balloonexpr' in a terminal.
Solution: Add 'balloonevalterm' and add code to handle mouse movements in a
terminal. Initial implementation for Unix with GUI.
Problem: Terminal debugger jumps to non-existing file.
Solution: Check that the file exists. Add an option to make the Vim wide
wide. Fix removing highlight groups.
