svn commit: r349346 - head/usr.sbin/kbdcontrol

[Warner Losh]

Author: imp
Date: Mon Jun 24 21:05:14 2019
New Revision: 349346
URL: https://svnweb.freebsd.org/changeset/base/349346

Log:
  kbdcontrol -h prints two error messages.
  
  We loop through getopt(3) twice. Once for -P args and once for the
  rest. Catch '?' and print usage when that happens.

  head/usr.sbin/kbdcontrol/kbdcontrol.c
