Re: Bug Report (Feature request?) etags (GNU Emacs 21.1)

       3) additionally, and as a separate improvement, when told to parse files
          X and Y, where Y contains #line directives pointing to X, do not tag
          X.  This allows to use `etags zz.y zz.c', and etags will only tag
          zz.c, and generate tags pointing to zz.y.
   
   That is backwards.  It should only tag zz.y, not zz.c.
   
   The reason is that zz.y may have tags that are not reflected in zz.c.

Argh.  Right.   
                                                  It will also be possible
          to use `etags xx.web xx.c' and etags will only tag xx.c with tags
          pointing to xx.web.
   
   That is reasonable in this case because xx.web is in a format that
   can't be processed by etags.
   
So etags should distinguish the two cases.  I'd like to find a more
linear logic, however.
