As a result of this, I now get:
zsh -fw
cd /
zsh: path expansion failed, using root directory

So if the directory starts as / the !*xbuf test succeeds and it prints
the warning. I'm not sure whether it would be better to skip the whole
xsymlinks call for a path of "/" or to check the return status from it.
