can it be considered a bug if file(1) on certain files produces =
multi-line description??

if your filesystem is stuffy enough you can reproduce this with =
something like
find / -print0 | xargs -0 -n1 file | grep -C2 -v '^.*\: .*$'

multiline descriptions in file(1) are inconsistant with overall design =
of system.  They raise additional difficulties in automatic scripts.
