Changed return value of git_oid_match to be consistent with the other…
… compare methods (0 means oids match). Added method to compare prefixes of hex formatted oids.

I don't like this. You apparently feel differently, but for me a function with match in it means "does it match?" so I expect a "true" response if they do. A compare, on the other hand, means "what's the difference?" so I expect a zero if the difference is none, i.e. they are the same.
Furthermore, why is there a
git_oid_match
and agit_oid_cmp
if they are pretty much the same?da03c9f

Returning 0 in case of a match fits the model set by standard functions like strcmp and memcmp, so this makes sense to me.

@pegonma fair enough, there is indeed a point to the extra function, mea culpa for not spotting that, but then IMO a better name would be
git_oid_ncmp
so it fits in better, as it does the same asgit_oid_cmp
but only up to a certain amount of chars.
