[uw.mfcf.software] xh-makefile-body now handles packages with no local files

rblanders@watmath.waterloo.edu (Robyn Landers) (09/15/89)

Discovered that xh-makefile-body crapped out on packages with
no local files or directories for it to complain about.
(I think it's been like this all along...?)
Fixed and tested on packages with and without local files/directories.
RCSed.
