Re: RFC: New diff-delta.c implementation

That's about how I implemented it in my last patch.
Is it correct that 0 means that there is no max_size?
Should I set *delta_size to 0 when doing an early
return, or leave it alone?

When failing, I think
the convention is to return NULL and what you do with *delta_size
does not matter, but Nico and pack-objects.c code can answer
that better than I can ;-).

Note that this really is a micro-optimization,

True.  max_size is a hint, and the caller validates the size
independently anyway, so ignoring is fine.
