Odd apparent cursor movement in mintty (+emacs)

Odd apparent cursor movement in mintty (+emacs)

[Gary]

In some file^H^H^H^Hbuffer in emacs(-nox), with mintty maximised, cursor
movement appears incorrect - moving the cursor forward[1] (emacs'
forward-char via C-f / cursor right key) incorrectly positions the
visible cursor 'n' characters forward. The insertion position is
correct, however - it only moves one character forward.

emacsclient 23.2, GNU Emacs 23.2.1, if it makes any difference.

[1] backward, too, but up and down seem unaffected

Do you have any non-ASCII characters on the affected lines? If so, it 
sounds like a mismatch of character encoding between mintty and emacs' 
assumption. What's your locale environment variables?

In that case wouldn't it also happen when mintty was not maximised? It
doesn't.

Can you give a precise recipe (as simple as possible) for reproducing 
this problem?  I just started emacs in a maximized mintty window and had 
no problem with cursor movement.

Quoting Simon Tatham yet again: "In bug reports, try to make very
clear what are actual facts and what are speculations. Leave out
speculations if you want to, but don't leave out facts."

So please do answer Thomas' questions. If possible, attach the file
that shows the problem.
