Most systems support -WIDTH option which is an abbreviated form
of -w WIDTH or --width=WIDTH option, but some OS don't support
-WIDTH format.
As far as I've checked (on actual systems or online manpages),
Linux/FreeBSD/DragonFlyBSD/OpenBSD/Solaris/AIX/Cygwin support
-WIDTH format, but NetBSD doesn't support this (see below).
IRIX and HPUX may not support either according to online manpages.
-w WIDTH format is basically supported by all systems that have
fmt command, so this is probably better in terms of portability.
