cvs2svn has significant problems with copy identification.
If mozilla has a lot of branches, tons of them will end up with entire
adds of the full text of the files as the first revision on the branch,
instead of copies from the approriate sources.

This happened to gcc, and by numbers, about 4 gig of our repository is
wasted space from this.
