I just thought of a semi-realistic use-case : diff.*.{command,textconv}.
One may want to allow per-project sets of diff drivers, but these
variables contain actual commands, so clearly we can't allow any
value for these variables.
"semi-realistic" only because I never needed a per-project diff driver,
I have my per-user preference and I'm happy with it.
Anyway, the feature does not seem vital to me, but if someone comes up
with a clever way to keep room for it in the namespace, that would be
cool.
