Unfortunately, 'fold -s' != 'GNU fmt -s'

0 ~>printf '   q w e r t y u i o p\n' | fold -s -w 10
   q w e 
r t y u i 
o p

0 0 ~>printf '   q w e r t y u i o p\n' | gfmt -s -w 10
   q w
   e r t
   y u i
   o p

BTW, fmt utility shipped with Solaris9 and Heirloom fmt
works like GNU fmt. FreeBSD and OpenBSD use -s option differently.
All fmt utilities I've seen support at least -c and -w.
