Re: #line compiler directives in results.

I've decided it is probably easier to work-around my issue within my
editor.  So I just created an emacs function which parses the #line
directive (after using gtags-find-tag) and loads the referenced file and
line number.  This seems almost as good as post-processing the tags file.

Thanks
