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

Hello Francesco,

Great, thanks!

Hmm.  One problem though, although I'm not sure how to handle this:  

I create the tag-file using something like:

find . -name "*.c" -exec etags -a -I -o /home/utcke/src/StreetSigns/TAGS {} \;

probably not the most elegant way to do this (something featuring
xargs would probably be preferred), but it works.  Only: the TAGS file
now contains entries like the following (I'm replacing the non-ascii
characters with a look-alike ascii representation...) 

^L
Canny/Khoros/kedgelio.c,21
#define MIN(^?MIN^A1,0
^L
kedgelio.web,226
static char rcsid[^?597,
boolean kread_edgels(^?54,
[...]

This is because the #line directives in Canny/Khoros/kedgelio.c read:

#line 590 "kedgelio.web"

But of course in the TAGS file it should read
Canny/Khoros/kedgelio.web instead of kedgelio.web.  Possible
solutions:

a) Get fweb to output absolute paths.
b) Have etags prefix the filename from the #Line-directive with the
   current path.
c) Something else?

I'm not sure what would be the best thing to do here, as both a) and
b) would prevent me from seperating the *.c from the *.web...
