I did not spell the specifics out because this change won't happen in any
near future anyway, but my thinking was to give a way for "add -p" to
either (1) internally run without quotepath regardless of the user's
settings or (2) unquote the paths correctly when it learns the set of
paths affected by the change.

I think the right approach is (2), because you need to unquote pathnames
with some byte values that even with core.quotepath=false will not pass
unquoted *anyway*.

I also happen to think that it may be a good idea to ignore core.quotepath
settings in format-patch, but that is a separate topic.
