I've tried to remove (= (match-beginning 0) (match-end 0))
and then tried the test case provided by Drew,
but it goes into an infinite loop.
So it requires advancing by 1 char - the same trick as it's used
in query-replace, etc.
Also I noticed that Drew's test case matches at 'eob'
that is wrong. So I moved checks for bobp/eobp outside.
The third problem I noticed thanks to Drew's test case
is that lazy-highlighting incorrectly highlights empty matches.
Fixed as well.
