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.

If the schema changes after 20171114162227 for any of these models, and specs
after this one use factories, then those factories will use the models with
outdated column information cached.

We shouldn't really use factories in migration specs, but this is a special case
because there is a lot of git-related setup code in the model that would be
painful to copy to the migration. Instead, we just manually reset the column
information for the models we could pollute.
