I can be git champion for "Better SCM Initiative" comparison... although
I'd rather somebody else was it.

I'll try to send revised patch soon. Integrating commentary is a bit
harder that it could be because some responses were sent _only_ to
git mailing list, so I'd have to browse through git mailing list
archives.


BTW. some of the questions / comments were caused by the fact that the
features listed in Better SCM Initiative: Comparison are a bit ambiguous.

What does for example "Atomic Commit" mean? Does it mean that if we
interrupt commit in the middle we would always get full commit or none,
and not some f**d-up intermediate state? Hos CVS can have atomic commits
then?

What does "Renames Support" mean? Does it mean that when browsing history
we [can] show file / directory renames? Does it mean that log of file or
directory history [can] follow renames? Does it mean that line-wise file
history [can] follow renames? Renames support in merges is as TODO, so
I don't think that this one matters in this question. Because the answer,
especially in the case of git which is a bit different in that it does
rename detection and not rename tracking (using inodes / file-ids),
depends on that...
