    Why would that matter?

So that it won't actually load the version that causes trouble.
With semantic, that causes hangs, right?

    That sounds like a lot of work for very little benefit: currently files are
    loaded by doing an `fopen' and then reading and parsing directly from there,
    so it's never put into a buffer where a search could take place.

It won't be a big loss to read the whole file and search it before
loading it, if we only do it for a few recognized file names.
