[PATCH v3 0/3] Document diff and filter drivers in config

What changed since v2:
- I decided to move the diff.* configuration options into a dedicated
  diff-config.txt, corresponding to merge-config.txt.
- The placeholder <driver> is much less confusing than <tool> (see
  difftool.* family) -- thanks to Michael for that.
- Language is much nicer now- thanks to Michael again.
- The deprecated `funcname` is excluded now. Thanks to Jakub.
- There's one extra patch; a small inconsistency that I happened to
  come across while comparing diff-config.txt with merge-config.txt.

Thanks for reading.
