Much better.
If we anticipate that we may add _more_ ways to find the thing
later, then I would say this code structure is better:
/* Is it at the beginning of the buffer? */
found = skip_prefix(...);
if (!found) {
/* Oh, maybe it is on the second or later line? */
found = ... find it on a later line...
}
if (!found)
continue;
but I do not think that is the case for this particular one. We
either try to find it at the very beginning (i.e. no leading
newline), or we have some other lines before it (i.e. require
leading newline), and there will be no future extension, so what you
suggested below looks sensible.
