If I remember correctly, it was me who proposed this change.  S-TAB is
consistent with desktop environment where Shift is commonly used as a
`reversal' modifier.  I.e. TAB moves forward, S-TAB moves backward.

I'm not proposing to unify Emacs shortcuts with `standard' ones, like
Ctrl+F for search, since Emacs is, eh..., Emacs :)  But in some cases
this is useful and S-TAB is one of them.  S-TAB is normally unused in
Emacs anyway and, as has been mentioned, there couldn't be any conflicts
since S-TAB cannot be typed on a tty.

Of course, there is nothing wrong in keeping M-TAB in Info mode with
the same functionality, but, please, let's not reverse the S-TAB
addition.
