Allow using less horizontal space in TUI source window
The source window currently uses a field width of 6 for line numbers, and it further aligns to the next tab stop. This seemed a bit wasteful of horizontal space to me, so I changed that in an earlier patch. However, that change wasn't universally popular. This patch instead adds the option to use less horizontal space in the TUI source window. gdb/ChangeLog 2019-12-01 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_copy_source_line): Add "ndigits" parameter. * tui/tui-winsource.c (tui_copy_source_line): Add "ndigits" parameter. * tui/tui-win.h (compact_source): Declare. * tui/tui-win.c (compact_source): New global.
