help config: explain that config files do not exist by default

Inspired by critique given on StackOverflow where a user writes:

  I can have a good guess at what "%USERPROFILE%" might signify but
  none of the files listed in the "hg help config" output exist after
  running the installer. Previous experience would suggest that
  missing files mean something somewhere has gone seriously wrong.
