I said "at least" because I suspect this is far from sufficient.
When the variable is set, there is no way to say "do not bother
signing commits when stashing WIP changes", for example, no?

Scripted Porcelains that happen to use commit-tree are all affected,
while those that have been rewritten in C and internally make calls
to commit_tree() (e.g. "git merge") will not be affected by it.  I
still am not convinced that this configuration variable is a good
idea in the first place, but I am not its audience, so....
