"If your mercurial/templates/ directory is dirty, then the template
system would otherwise import duplicate templates from the .orig files
and potentially try to parse .rej files.

Since editing/reverting these templates isn't an unexpected action,
and since they're in .hgignore, it's best that the template system
know to skip them."
