The trouble is that there's no way to tell cvs2{svn,hg} to continue
converting from r2521 (or wherever it left off).  That's deeper in the
infrastructure than my code.

Huh. Works for me. E.g. in my cvs2svn working copy:

  $ rm -rf main.hg
  $ ./cvs2hg --existing-hgrepos main.hg test-data/main-cvsrepos
ERROR: directory 'main.hg' does not contain a Mercurial repository

That is expected and intended, but rather lame.  (I was slavishly
imitating the behaviour of cvs2svn --existing-svnrepos.)

But then:

  $ hg init main.hg
  $ ./cvs2hg --existing-hgrepos main.hg test-data/main-cvsrepos

works fine.  I can even convert the same CVS repository twice into
main.hg ... which is completely stupid, but it works!
