1.2s is pretty slow for this purpose.

Otherwise it would be possible to use this approach (by introducing a 
Grep-specific location type) and avoid parsing the line contents for 
every match.

One downside would be missing on the syntax highlighting which we 
sometimes get for already-fontified parts of buffers, but it's 
unreliable anyway.
