I was talking about grep. And if you teach etags about ":" you can
teach it about shorthands, too.   Again this comes with the problem,
I don't think it's even worth discussing.

It's like hunger. The daily problem "hunger" is not solved by "eating".
It's solved by dying, I presume.  That sucks, unless you're a zombie
in which case you're still hungry.

Heh, sounds a lot like advocacy to me. Anyway, it's hideous, IMHO.
Even if you think that's just taste (it might be), the main reason
I'm not interested in discussing it is that it doesn't solve the s.el, f.el,
dash.el situation at all, because it's not a namespacing system.

The actual symbol is always the longhand version.

We can try to guess notable cases like s.el if they use the cookie
;; Package-Requires or even by watching the "require" calls.
Anyway, even if we don't do that, adding a couple of lines
in a backward-compatible way is infinitely better than renaming
a zillion calls.
