I have set up Emacs to be the EDITOR for bzr via emacsclient (yes, I'm
invoking bzr from the command line).  That works, but every time I
commit a file to upstream, Emacs bitches with the following message in
*Messages*:

First, it turns out this happens on GNU/Linux as well, at least if one
invokes "bzr status" while "bzr ci" is waiting for emacsclient.

The solution, suggested by John Arbash Meinel on the Bazaar mailing
list, is to patch msgeditor.py, a bzr module, as shown in the patch
below.  This will cause Bazaar to create the bzr_log.* files in the
system temporary directory, so Emacs will not try to run "bzr status"
on it.

If you are on Windows, and installed Bazaar with a standalone
installer, then you will need to download from the Bazaar site the
sources of Bazaar that correspond to your installed version.  Then
locate library.zip, remove from it bzrlib/mzgeditor.pyo, and add the
patched bzrlib/mzgeditor.py.

If you are on Unix or GNU system, you will need to talk to your
sysadmin about replacing msgeditor with a patched version.
