A replacement obviously not. show_changed_revisions already calls
show_log once, where I'd like it to call it twice.
But if they were less public functions in bzrlib.log, it would be
easier to refactor them so that show_log is used consistently
It's already an anomaly that 'pull' and 'push' use
show_changed_revisions where 'missing' use its own functions.

aaron> There's no way for a user to specify a log format
Yet. But I did an RFC about the showing revisions in a consistent
way across all bzr commands and that includes allowing user to
specify their preferred log format from the command line (in
addition to the one you care and love in branch.conf :).
And I voted approve on your previous patch regarding pull partly
because you were making the log_format visible just where I
wanted it :-)

I didn't say it was bad, quite the contrary: "Very nice one".
I said: please, stop adding public functions in bzrlib.log, there
are already too many there, even some evil ones that nobody
should use (find_touching_revisions for example). I plan a
deprecation dance there which will already be painful, have

It's a combination of _linear_view_revisions + show_log.
Sorry I shouldn't have say 'clearly', I'm knee-deep (sp?) in
log.py these days...
In summary: I didn't vote reject, this is better than what we
have. I didn't vote tweak either because I thought I was asking
too much for a bare tweak. So I voted resubmit asking for the
functions to be made private so that the work I plan to do on log
is not made more complicated than it already is.
