Thanks for testing.

We could use abbreviate-file-name, perhaps.  But I'm not sure the
change you describe is not for the better, since absolute file names
are absolutely understandable and interpreted correctly in all
situations, whereas file names that begin with "~/" need to be
interpreted either by Emacs or by a reasonably functional shell before
they can be safely passed to any other program.

I'm curious what does Dmitry think about this consequence of the
change.
