This seems a bit fishy to me. In the strcoll counterpart, POSIX states
that strcoll must not set errno to 0, and that the value of errno is
unchanged on success (an app desiring to check for failure must set errno
to 0 itself before calling strcoll). For consistency, would it be better
if we changed memcoll to behave likewise? On the other hand, I guess we
did document in memcoll.c that memcoll explicitly sets errno to 0 on
success, making memcoll not quite like strcoll.
