You mean, like <branch>-start tags?  I have one of those for every
release branch in my CVS repo (~40 of them), and I don't seem to have
duplicate fixup commits in my Mercurial output.

Hmmmmm.  I wonder if this has anything to do with my cute "sloppy
fixups" hack.  The idea of sloppy fixups is to suppress a fixup that
only deletes files, since that is almost certainly a CVS partial tag.
Anyone using Mercurial (or git or, probably, svn) from day 1 probably
would not go to the trouble of tagging only part of the tree, so IMHO
"idiomatic" conversion demands a way to turn partial tags into plain
ordinary tags (ditto branches).

See http://vc.gerg.ca/hg/cvs2svn/file/tip/README.cvs2hg for details.
It's implemented in
http://vc.gerg.ca/hg/cvs2svn/file/tip/cvs2svn_lib/hg_output_option.py
-- search for "sloppy".  There might also be some cooperating code in
dvcs_common.py in the same repo.
