Yes, it's a valid observation.  With a CONST VARYING parameter, the
compiler doesn't really need OPTIONS(*VARSIZE) to know it is safe to
pass a shorter parameter without copying it to a temporary.  The called
procedure isn't supposed to access beyond the passed length of the
string, so it doesn't matter what, if anything, is passed beyond the
valid length.

Best practice?  Hmm.  Another compiler might not make that optimization
without being told *VARSIZE, so I guess it's a good idea to code both.
