Previously reported bug with UA:ASSEMBLE

[Moon at MIT-AI (David A. Moon)]

This happens in 43.0 also.  I fixed it with a kludge, you should look
at the function (in LISPM;CADRLP) and figure out what the right way of
doing it is.  There doesn't appear to be an adequate replacement for the
old SI:FILE-GET-FILE-INFO function.
