Re: [PATCH/RFCv3 2/2] receive-pack: don't pass non-existent refs to post-{receive,update} hooks in push deletions

Do you have to have these separately only to keep track of the corner case
errors?  I would have expected that it would be more natural to mark them
by adding a single bitfield to "struct command".

This is not an "invalid" delete but deleting a non-existing ref.  Perhaps
you would want to move the warning and optionally reword it as well, e.g.

	if (!parse_object(old_sha1)) {
        	old_sha1 = NULL;
                if (ref_exists(name)) {
			rp_warning("Allowing deletion of corrupt ref.");
		} else {
			rp_warning("Deleting a ref that does not exist.");
			cmd->did_not_exist = 1;
		}
		...
