Creating the log file in the working directory is also consistent with
arch and baz.

One reason to put it there is that the working directory may be more
protected against losing the user's valuable commit message -- for
example some linux distros have /tmp in tmpfs (a ramdisk) or
automatically erased at startup and so a power outage will lose their
commit message.

Perhaps it would be enough to make it in TEMPDIR and print the name if
the commit is aborted?

It does seem curious and unusual to me, but the original poster said he
was controlling files in /etc.  It's reasonable to run bzr as a non-root
user to record a history of files that that the user cannot themselves
modify.

There may be some other assumptions in the code that the working
directory is writable.

It's OK with me to either always use /tmp or try both.  On the whole
people who want the arch-style behaviour may be better off just doing
'commit -F .bzr.msg', which I sometimes do.
