I think we just need to have callers of grep_source_init provide us with
the actual pathname (or NULL, in the case of GREP_SOURCE_BUF). That is
where the information is lost.

Yes.  I agree that is the right approach.

Passing full path this way means prepare_attr_stack has to walk back
to top directory for every files (even in the same directory). If
.gitattributes are loaded while git-grep traverses the tree, then it
can preload attr once per directory. But Jeff's approach looks
simpler.
