help config: explain that config files do not exist by default
Inspired by critique given on StackOverflow where a user writes:

running the installer. Previous experience would suggest that
missing files mean something somewhere has gone seriously wrong.

If there is a per-repository configuration file which is not owned by
the active user, Mercurial will warn you that the file is skipped::
