Re: Remove help advice text from git editors for interactive rebase and reword

While these reminders are useful for new users, with time they learn
what the score is, and experienced users might find these advices are
just wasting a couple of lines' worth of screen real estate.

Make displaying these advices configurable via the 'advice.commitMsg'
config variable.

It may not be a bad idea, but the code after the patch does look
ugly with too deep indentation levels.  Can some refactoring help, I
wonder?

Is that advice.commitMsg?  It looks more like commitEditor advice to
me but it may be just me.
