Let's not make a mole out of a molehill -- it will be all right. After all, the 
change is for the better.
Surely we must be able to correct past mistakes?

Remember that this is not a new notation -- 'kbd' has always accepted it, and 
I'm sure that .emacs files the world over contain instances of it. The manual 
uses it a bit everywhere, and rightly so. I'm quite sure that nobody ever got 
confused by it.

Actually it makes sense to let the logical notation be the default, doesn't it? 
There's no harm in trying it on master.

The NS port renders <backspace> as the backspace symbol (etc), by convention 
for that platform. This is done by string replacement and won't work if the key 
is <M-backspace> instead of M-<backspace>.

Of course we can add messy code to correct for this, but why do that locally in 
the NS port for this specific purpose when everyone could benefit from a 
clearer notation in the first place?
