Simplifying the conversion

[Eric S. Raymond]

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:address@hidden
revno:116031 -> {2014-01-15T08:22:41Z}

The spirit of resistance to government is so valuable on certain occasions, 
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 
rebellion now and then. -- Thomas Jefferson, letter to Abigail Adams, 1787
