Why use the helper only for this one?  Aren't existing calls to
starts_with() in the same if/else if/... cascade all potential bugs
that the new helper function is meant to help fixing?  For example,
the very fist one in the cascade:

	if (starts_with(name, "refname"))
        	refname = ref->refname;

is correct *ONLY* when name is "refname" or "refname:" followed by
something, and it should skip "refnamex" when such a new atom is
added to valid_atom[] list, i.e. a bug waiting to happen.  I think
the new helper is designed to prevent such a bug from happening.

I fully agree, but I also think that this should be a separate topic.
