Well, that (mostly) sorted listed still helps to find out a little 
quicker whether a specific tool that can do both merging and diffing is 
already in the list. At least that's the case for me.

Sounds like a good idea now that you've added "git mergetool 
--tool-help". But I'd like to save this for a future exercise to not do 
too much stuff at the same time.
