Additionally, I should add that I keep a checkout of each branch in
its own directory.  For example: erc/emacs22 (erc--emacs--22),
erc/arch (erc--main--0), erc/arch-5.1 (erc--rel--5.1).  This makes it
very easy to do sanity checks (diff -u against two directories) to
make sure that every desired change has been merged.
