Suppose I get a source package Z from you in which there is a file xyz.c 
which is generated from some file xyz.dum which is NOT included in
the package.

Now, what should etags do with the #line directives in xyz.c ?

Should it generate the TAGS file with references to xyz.dum
(i.e. nowhere as far as I am concerned), or should it make references
to xyz.c (which might make some sense to me)?

Alternatively, etags could put dual references into TAGS -- one for
the .c file and one for the .dum file, at least that would give me
a chance to find both  [in some cases, looking at the generated code
is necessary].

But I guess that if we have a command line option to control this,
then everybody will be happy!
