Subject: [PATCH] test: Don't mess with user's HOME directory

This was too rude of a thing to do and could easily introduce
problems, (as reported by Rob Browning whose environment required some
HOME-specific things for shell startup).

Instead, implement more focused changes to ensure that particular file
in $HOME don't cause problems. Specifically, we fix known problems
with ~/.signature and ~/.mailrc here.
