   etags will already do this if you run it on parse.y and parse.c.
   I've always found this a bit annoying.  Usually I use some Makefile
   rule I didn't write to generate TAGS.  So parse.c is included, but I
   don't want it, since I never want to edit it.  In this scenario it
   would be convenient if etags ignored the generated file.

I suppose you mean a rule like this:

if etags finds a #line directive in file X pointing to file Y, and if
file Y is given on the command line, then ignore file X.

Maybe this would better be handled by not giving file X to etags to
parse.  Should etags correct this common makefile error?  By the way, it
wouldn't be so easy, as currently etags processes files independently of
each other, in sequence.

Going back to the original question, what happens if you give to etags
the original .web file, instead of the .c produced from it?
