rename: add hint about --at-rev if source file doesn't exist

It's quite common that users want to record copy (rename) information
after committing the working copy changes (i.e. an added and a deleted
file). When they try `hg mv [--after] <src> <dst>`, that just fails
because the source file doesn't exist. It seems helpful if we can
point them to `--at-rev=.` in this case.
