I'd rather do it like that too but I don't think it'll work. The
trouble is the entries are evaluated when searched and ASDF may not
know that an entry is nil until after it does the evaluation. The
entry in question is
'(let ((home (sb-ext:posix-getenv "SBCL_HOME")))
(when (and home (not (string= home "")))
(merge-pathnames "site-systems/" (truename home))))
and I think that we can't know whether or not this entry is valid
until after we've put it on the *central-registry*.
So..., I'm going to set up the iteration so that nil entries are
removed during the search and leave the SBCL portion as is.
