Igor,

OK, but then why did you tell me this:

>This is an option of "vim" itself.  In vim, "help title".


Really, it's of little consequence to me, but here's an excerpt from 
the Vim on-line help text:

Only works if the terminal supports setting window titles
(currently Amiga console, Win32 console, all GUI versions and
terminals with a non- empty 't_ts' option - these are Unix xterm and
iris-ansi by default, where 't_ts' is taken from the builtin termcap).


I know very little about termcap or terminfo (nor which of them Vim 
uses), but if I cared enough about why this appears not to work for me, 
I'm sure I could figure it out.

Here's a clue. Vim's ":set title" and ":set notitle" work if I invoke 
Vim thusly:

% TERM=xterm vi

The title string is restored to it's initial value and reset to Vim's 
titlestring setting when Vim is suspended and resumed (resp.), too.

So it seems the termcap and / or terminfo descriptions for TERM=cygwin 
could have the necessary capabilities added (apparently identical to 
those used by xterm) so Vim could control the window title under the 
Cygwin console.
