OK.

I see. To tell the truth, I didn't bother to change $HOME outside Emacs and
start emacs -Q again to test the case other than HOME = "c:\\". I did try
using `setenv' to change "HOME", but that apparently doesn't have an effect
here. That is:
(setenv "HOME" "d:/usr/eli")
(abbreviate-file-name "d:/usr/eli/foo/bar") => "d:/usr/eli/foo/bar"
So, I didn't notice that it does work properly. Setting $HOME in Windows
itself to "d:\eli\" and then starting emacs -Q, I do get what you showed:
(abbreviate-file-name "d:/usr/eli/foo/bar") => "~/foo/bar"
So, I was mistaken - no problem. Thx for the clear explanation.
How about mentioning in the doc string that "~" is not substituted for the
user's home dir if that is the root. ("/" in Unix or Linux,
"<drive-letter>:\" in Windows)? The doc string gives an incorrect idea of
what the function does, in this case (which is common in Windows).
