In git in general, yes --- for example, 'git diff --src-prefix=""
HEAD^' tells "git diff" to leave off the usual c/ prefix in the
src filename it prints.

In git-svn, --trunk="" or --message="" might be meaningful, but not
nearly as much as --prefix="".

Another possibility would be to require Perl 5.8.9 or newer.  It was
released in 2008.
