It's working starting from zsh -f just loading compinit, too.  I tried
another vanilla version of zsh just to make sure.

If the other part of the thread doesn't yield anything, could you see if
you can find what's breaking it, in terms of shell settings or environment?
(To be quite clear: I'm not going to be doing this myself without some
indication of what to do.)

This isn't a proper fix.  If you want to play along, read and digest the
description with my first patch.  The key point is to keep ~-expansion
working.

However, this form does certainly have the globbing problems you pointed
out.  $~ is doing multiple things not all of which we want; I wonder if
this might be causing other problems, too.  It's annoyingly hard to get the
effect of file expansion and removal of quotes without the effect of
globbing, but a scalar assignment with $~ and an explicit unquote seems to
do the trick.  Does changing it along the lines of this patch fix the
original problem?
