Oh. So your example is a direct equivalent. Thanks.

I looked at 'grep -zo', but it doesn't seem suitable for our purpose: 
there's no way to make it output the correct line number. So we'd have 
to load each file in Emacs fully and search it them through ourselves a 
second time.

It looks like a better choice, but it's not installed on most systems 
AFAICT (it wasn't on mine), and xref doesn't really know what to do with 
multiline matches anyway yet (?).
