Hi folks,
there is a small but nasty bug in commands/file.c which causes it
to dump core on empty files. The case of zero length files is not
tested for and thus drives the type-guessing for-loop mad ...
The fix is easy, see patch below. And it makes it conformant to the
behaviour of the file commands I'm used to on BSD and SysV.
Bye
Detlev
