Hi,

When I invoke C-x C-f, clear the minibuffer, enter a remote file
name like "/frp.example.com:~/foo", and type C-a or C-b in order
to correct the host name to "ftp.example.com", I cannot move the
point to the place before "~" or ":".  Only <backspace> does it
but I have to retype the whole host name.  In addition, I usually
did `C-x C-f C-a C-k C-g' in order to copy the directory name of
the dired buffer to the kill-ring.  Is there a way to make it
behave like Emacs 22.1?

Thanks in advance.

No idea what's actually going on, but this is clearly a bug (not just an
annoyance, though it's certainly an annoying bug :-).

tramp-rfn-eshadow-update-overlay uses narrowing in a way that moves
point (the old point was outside the limits). It needs to save-excursion.
(This patch also replaces a call to `widen' with save-restriction.)


2007-10-17  Johan Bockgård  <bojohan@gnu.org>

	* net/tramp.el (tramp-rfn-eshadow-update-overlay): Save excursion.
	Use `save-restriction' rather than `widen'.

Your patch looks OK to me. Please install it (or tell me when I shall do).
