Oh, right. I never use a regexp that can match nothing, so I missed

You never use '*'?
I guess he meant "match *only* nothing", most of the time using *
you'll still use it in combination with a non-empty pattern. Easy to
miss that only [something]* can match nothing and therefore first
matches at the start of the line.
Yes, that's what I meant. I can't imagine where that would even be useful.
