commit: save the commit buffer off when parsing a commit

object.

A fair number of the users potentially want to look at the
commit objects more closely, and if you worry about memory
leaking in certain applications, you can always do a

	free(commit->buffer);
	commit->buffer = NULL;

by hand after parsing them.
