[PATCH] Fix ALLOC_GROW calls with obsolete semantics

[Jeff King <peff@peff.net>]

ALLOC_GROW now expects the 'nr' argument to be "how much you
want" and not "how much you have". This fixes all cases
where we weren't previously adding anything to the 'nr'.

This is on top of the add-empty topic in next. Your other uses of
ALLOC_GROW are presumably OK since they were already adding in extra
space.
