Looking at 'ktrace -i ...' of a typical call, it looks like NetBSD's
'getopt' is doing something wrong.  The script 'a2ps-lpr-wrapper'
contains:

TEMP=$(getopt -o d: -n 'a2ps-lpr-wrapper' -- "$@")

and the ktruss output shows:

[...]
 9654   9654 getopt   CALL  write(1,0x73f4fc19ae00,0x1e)
  9654   9654 getopt   GIO   fd 1 wrote 30 bytes
       " -- d: -n a2ps-lpr-wrapper --\n"
  9654   9654 getopt   RET   write 30/0x1e
  9654   9654 getopt   CALL  exit(0)
  2529   2529 sh       GIO   fd 3 read 30 bytes
       " -- d: -n a2ps-lpr-wrapper --\n"
  2529   2529 sh       RET   read 30/0x1e
[...]

which causes 'a2ps-lpr-wrapper' to terminate option processing
(the first "--"), and take the rest of the list as files to print.

This command line is then passed to 'lp', which passes it to 'lpr',
which then attempts to open these supposed files, producing the
error message above.
