Except, um, we still need to fill in the "summary" attribute for all
matches, so that there is something to display in the Xref buffer (the
line contents around the match), and the -o flag strips those.
And if we were to use the '.{0,100}file.{0,100}' trick, it messes up the
location of the match, the reported byte offset become unreliable. Also:
grepping for that kind of regexp is noticeably slower than grepping for
'file'. Or even '.file'. Like 85ms vs 7ms slower.
