Nit: IMO having `{{.*}}` to swallow extra path components is slightly preferable, as that avoids the filename being part of a regex. Almost certainly not ever going to be a problem, but it reduces what can go wrong. Does your environment also have trailing components after the line number? If there's any whitespace between '5' and the extra text then FileCheck will (99% confident) ignore those anyway.

Similar thoughts apply to all the other similar regexes.
