Re: [PATCH] Shallow clone: low level machinery.

Hi,

apart from my thinking this is not backward-compatible (you are supposed 
to be able to pull from a complete repo, even if it has a 
non-shallow-capable upload-pack), here are my comments:

- it is good that MAXPARENT and struct commit_graft are in more public 
	places now.

- reparse_* is misleading. Nothing is reparsed, but rather "unparsed".

- I'd hesitate to let git-daemon write temporary files. That is a whole 
	new can of security worms.

- It looks wrong to me to define MAX_PARENTS as 20 in upload-pack.c, when 
	MAXPARENT is defined as 16 in cache.h.

- The custom_graft issue could be handled in a more elegant manner if 
	git was lib'ified (no temporary file). Since that is already the 
	plan, why not do that first, and come back later?

Ciao,
