Subject: size_t vs "unsigned long"
Message-ID: <7vabr0djqr.fsf@gitster.siamese.dyndns.org>

Traditionally, inside git, we have used the length of things
with "unsigned long" for pretty much anything, except where we
wanted the length exactly sized we used int32_t, uint64_t and
friends.

A few places pass pointer to unsigned long as the second
parameter to strbuf_detach(), triggering type mismatch warnings.
An easy way out is to change strbuf_detach() to take a pointer
to ulong but I think it is going backwards.  Most places that
use "unsigned long" can safely be converted (and made more
correct) to use size_t.

Any opinions?
