convert: add support for specifying multiple revs

Previously convert could only take one '--rev'. This change allows the user to
specify multiple --rev entries. For instance, this could allow converting
multiple branches (but not all branches) at once from git.

In this first patch, we disable support for this for all sources.  Future
patches will enable it for select sources (like git).
