Translate gui=reverse to cterm=reverse
Until now, "gui=reverse" was translated to "ctermbg=fg ctermfg=bg", but Will Gray (graywh) pointed out to me that this is wrong, since there are many terminal emulators that do properly handle reverse video.

g:CSApprox_fake_reverse *g:CSApprox_fake_reverse*
|

In gvim, setting a highlight group like "Visual" (the color of your visual
|
||||
mode selection) to do reverse video results in it reversing the colors of
|
||||
each character cell under it. Some terminals don't support this and will
|
||||
instead always use the default background color on the default foreground
|
||||
color when asked for reverse video. If this variable is set to a non-zero
|
||||
number, CSApprox will change any request for reverse video to the "Normal"
|
||||
group's bg color on the "Normal" group's fg color, instead of asking the
|
||||
terminal to do reverse video. This provides a middle ground for terminals
|
||||
that don't properly support reverse video - it's worse than having the
|
||||
terminal properly reverse the colors of each character cell, but it's
|
||||
better than the broken behavior of some terminal emulators. This was the
|
||||
default behavior before CSApprox 4.0.
