This brings up another CVS problem, which I wonder if the SVN guys have
thought of:
cvsblame (or 'cvs annotate') is fantastic for finding out who wrote a
particular line of code. but when patches are reverted, the cvsblame
information gets lost, because the annotation shows the person who
*reverted* instead of the person (before them) who originally did the
commit.
Has anyone thought of trying to preserve the annotation information in
SVN? My current CVS-hosted project uses special tags (like @REVERT@) to
instruct a hacked version of cvs-blame. The final result can be quite
useful:

SVN ideas: provide a 'svn revert' command. This would check-out an old
version into the working copy, but also set a property on the working copy
indicating that this was a reversion. Then when the file is (possibly
modified then) committed, the property would exist to inform an annotation
tool of the true history of the file.
Possibly the 'change set' idea and some of the other SVN concepts can
accomplish this already. I'm just bringing it up because it's a recurring
CVS annoyance and I want to make sure the misfeature doesn't propagate
into SVN. =)
