We used to use ‘branch’ as the file to check for but moved away from it,
because it didn't work reliably with newer versions of mercurial (this
might have changed again in the meantime, since I don't follow
mercurial's development too closely).

Checking for ‘hgrc’ is not an option, because ~/.hg/hgrc is a possible
configuration file location, which would lead to false positives in the
user's home directory.

If a mercurial developer has an idea on how to properly detect this
particular extension, I'd be all ears. ;)
