NetBSD's current GNU Tar uses only 46 option letters and I can't imagine
what other options one could ever add to it.
SunOS-4's "tar" uses only 25 option letters, though it rules out four
more as impossible ().
V7 "tar" used 20 letters.
The "tar" defined by The Single UNIX Specification uses only 18.
