I wonder if this depend on your [1/5].  Isn't this actually a
simplification (removing 7 adding 5 lines) that applies to the
mainline already?  IOW, is there a downside of doing this
without any of the rest of the series?

rev-parse --git-dir would have said "fatal: Not a git
repository" already.  Do we still need to say "Failed to
find..."?
