Rather, you need to switch out of the TUI and back, with c-x,a.

Seems like you're not using git diff to generate the diffs
for some reason. If using GNU diff, could you make sure
to use the "-p" switch? It makes review a lot easier.

tui_refresh_all_win already calls tui_check_and_display_highlight_if_needed,
so why do we need to call tui_rehighlight_all? Is it the tui_update_variables
call that is really missing? But why would we need to call
tui_update_variables on CTRL-L, if we already call it when the user
changes the variables?

Please do this from the "set" hook of the relevant commands instead.
IOW, replace NULL below (and in the other commands):
add_setshow_enum_cmd ("active-border-mode", no_class, tui_border_mode_enums,
&tui_active_border_mode, _("\
...
NULL,
show_tui_active_border_mode,
&tui_setlist, &tui_showlist);

I don't understand this one. When is it ever necessary?
