Maybe, but it won't happen, even if it is better (which I'm not sure
it is).  Too many higher levels expect "~/foo" to keep is
HOME-relative form in Emacs.

Sorry, it's too late to change this.

Because it works, and doesn't cause any problems, and because by now
there are gobs of Lisp code that assumes this to be true.

(3) mostly, but also: this is done for a reason.  Users are happier to
see ~/foo in their file names and prompts than /home/whatever/foo.
Emacs uses these abbreviated file names for that reason.

Sure, so how about suggesting to the glibc developers that glibc
renames the corresponding APIs to use "true" instead of "real"?
