convert: raise Abort instead of NoRepo when CVS pserver auth fails.
At this point we know the source is CVS, so we should not go through
the rest of the converters.
# hg backend for convert extension
# Note for hg->hg conversion: Old versions of Mercurial didn't trim
# the whitespace from the ends of commit messages, but new versions
# do. Changesets created by those older versions, then converted, may
# thus have different hashes for changesets that are otherwise
# identical.
