Hello, all.

"mt status" can report "current file number: 0", but "mt asf 0" gives
an "illegal count" message. SUS2 seems not to talk about mt(1), but
Solaris, for instance, allows and does the right thing with "mt asf 0".

Does anyone object to "mt asf" supporting "0" as a valid argument?

A pretty minimal diff to accomplish this is attached, for your perusal.
