I can find no evidence that anyone ever dropped either a Bazaar or
CVS revision stamp anywhere in the source tree outside a Changelog.
I put it in that cautious a way because the search strings I have
to use to look for these generate a lot of false positives. It is
still possible that I have missed a true positive in the clutter.
Does anyone remember putting a revision ID anywhere outside a
ChangeLog or commit comment?
If there are no such instances, my life gets simpler and the
probability of one of these not getting lifted to a VCS-independent
form goes way down.
It also looks probable that in this repository so far, commit
timestamps are always unique *if* I do a clique-squashing pass
on the oldest part of the history first. I will check this property.
(Cliques eligible to be squashed are runs of CVS file commits with the
same timestamp and same committer.)
This is my current fossil-references list:

My next step will be to process this into a map from fossil references
to action stamps.
As I noted prevuiusly, it may turn out that all the action stamps in
the map have unique timestamps (that is, do not need to be
disambiguated by committer ID). If so, I may just use the RFC3339
form of the commit date, lightly decorated, as a reference.
To be concrete, the difference would be between these two styles of
replacement:
revno:116031 -> 2014-01-15T08:22:41Z!juri@jurta.org
revno:116031 -> {2014-01-15T08:22:41Z}

that I wish it always to be kept alive. It will often be exercised when
wrong, but better so than not to be exercised at all. I like a little

What patterns did you use to look for revisions, exactly? Here are a
few references I found:
lisp/cedet/semantic/bovine/grammar.el:146: ;; backquote (introduced in rev. 102591 in emacs-bzr).
lisp/url/url-handlers.el:97:(defvar url-handler-regexp) ; defined below to avoid recursive load (revno:108572)
lisp/progmodes/python.el:3295: ;; Inspired by imenu--flatten-index-alist removed in revno 21853.
lisp/vc/vc-svn.el:26:;; Sync'd with Subversion's vc-svn.el as of revision 5801.
The last one sounds like an svn version from some other repository.

They should be very rare, but see above.

This looks too short; I get 149 commit messages that specify bzr
revision numbers, and 25 more which look like CVS revision numbers.
Please show the command(s) you used to find these, it's possible you
are missing some options. I can show you the command I used, if it
will help.

Why not use the committer ID regardless? It's easy to get that from
bzr (it's part of the revision ID), and will allow you to avoid the
step of determining whether the time stamps are unique.
