Well, that's a bigger project than the 4-line patch you've suggested, 
and it requires manual intervention from the user. You suggested it 
before too, and I don't remember Eli being very enthusiastic.

That won't help when I'm inside Emacs sources; I still don't want to use 
tags for Elisp.

etags might be popular (so some sort a general solution might be 
welcome), but that doesn't mean it's used with Elisp a lot.

For instance, if we consider Debian-like distributions, 
https://packages.debian.org/jessie/all/emacs24-el/filelist does not 
include the TAGS file. I don't think the C sources are generally 
included in the binary distributions.

And if we're just talking about Emacs developers, I wonder why nobody 
else spoke up on emacs-devel or in this bug yet.
