[PATCH] builtin-fsck: fix off by one head count

According to the man page, if "git fsck" is passed one or more
heads, it should verify connectivity and validity of only objects
reachable from the heads it is passed.

But before this patch, when it was passed only one head, then it
behaved as if no heads were passed (that is it used the index file,
all references in $GIT_DIR/refs/* and all reflogs). In fact it just
ignored the first head it was passed.

It looks like this bug was introduced when "builtin-fsck.c" was
changed to use "parse_options" (commit
5ac0a2063e8f824f6e8ffb4d18de74c55aae7131).

	Sorry if you receive this patch more than once, but it
	seems that something did not work when I tried to send
	it to the mailing list before.
