11/5    Is there a way to make emacs' TAGS smarter about searches?  There's
        a type called foo_t.  I do a tags search within emacs for it.  It
        brings up the first instance where foo_t is used as the return type
        of a function.  That's useless for me.  I need to know how foo_t is
        defined.  Any way to make it work correctly?
        \_ One workaround is to use tags-loop-continue (ESC ,) after it finds
           the first instance.  Another one that might work is to specify the
           .h files before the .c files when you run etags.
        \_ grep.
