How do I customize finding references?

[shark-horse]

I don't see any way to inform gulp-rev-all about what constitutes a match to a file that will have a name change. Specifically, using the require-css plugin, say I have a requirejs shim with spectrum: ["css!../lib/spectrum/spectrum"]. That should be changed to e.g. spectrum: ["css!../lib/spectrum/spectrum.abcd1234"] using the hash of the CSS file at that location.

I looked at providing a custom replacer function, but from debugging, it looks like that runs once for every match, and the css! stuff isn't matched, so it would not run at all in file where that is the only match.
