We should use this limit everywhere, but especially in project search results,
where we could be highlighting very long single lines. (Typical examples:
minified JavaScript, and JSON data files.)

A file containing /:\d+:/ in its contents would break the search results if
those contents were part of the results, because we were splitting on colons,
which can't work with untrusted input.

Changing to use the null byte as a separator is much safer.
