bug#2233: [Aquamacs-bugs] viper-mode cursor color does not reset to red

I believe this is a bug in viper mode: if your present cursor color  
(the default is set in `default-frame-alist') is the same as `viper- 
replace-overlay-cursor-color' (by default: "Red"), then Viper forgets  
to save it before switching to insert mode.

The workaround is to set viper-replace-overlay-cursor-color to  
something like "red4".

The solution would be to implement `viper-save-cursor-color' cleanly,  
unless that's already been done for Emacs 23 (haven't checked).

(I'm going through old bug reports that unfortunately wasn't resolved at
the time.)

I was unable to reproduce this bug in Emacs 28, so I'm going to go ahead
and guess that is was fixed in the 12 years since this was first
reported.  If you're still seeing this problem, please respond to the
debbugs address and we'll reopen.
