Yeah, I think the GNU people managed to browbeat Linux distros into
standardising on ^? some time ago.

... and I can't change it to "mintty", because even if entries for it
were added to Cygwin's termcap and terminfo, any other system would
say "what?".

You could change it though, e.g.:

  mintty env TERM=3Dmintty /bin/bash -l

And then have a bit in your .profile that checks for that TERM setting
and changes it to xterm afterwards.

Alternatively, mintty can be recognised by querying the "secondary
device attribute". If you send "\e[>c", it will currently reply with
"\e[>77;501;0c". The 77 (ASCII 'M') identifies mintty, the 501 is the
version number, and the last field is unused.

Btw, how do you deal with the problem that the 'kbs' terminfo entry on
the remote machine doesn't necessarily fit the terminal on your local
machine?
