bug#7796: ^M in vc-dir

[Sam Steingold]

I am running bzr tip emacs on winxp64.
C-x v d emacs/trunk RET
produces a buffer:

=================================
VC backend : Bzr
Working dir: ~/src/emacs/trunk/
Parent branch      : bzr+ssh://sds@bzr.savannah.gnu.org/emacs/trunk/^M

Shelves            : No shelved changes

                         ./
                         lisp/
    edited               lisp/w32-fns.el^M
=================================

where ^M are the actual \r characters.
this breaks things, e.g., I cannot hit RET on the file name, I get the
non-existent file with a ^M in the name.
this does not happen with hg and svn.

(executable-find "bzr")
"c:/Program Files (x86)/Bazaar/bzr.exe"
(executable-find "hg")
"c:/Program Files (x86)/TortoiseHg/hg.exe"
(executable-find "svn")
"c:/gnu/cygwin/bin/svn.exe"

It doesn't happen for me with bzr, either.  What is
buffer-file-coding-system of this buffer?  It should be something-dos,
I guess it isn't in your case.

Also, can you see in your .bzr.log what commands is vc-dir invoking,
exactly, when you type "C-x v d"?

utf-8
I fixed this by reverting the effects of
(modify-coding-system-alist 'process "" 'unix)
which lived in my .emacs since I last used it on windows 4 years ago...

Great!  Closing the bug, then.
