veriexecctl(8) segfaults when no argument is given
veriexecctl(8) segfaults under -current. Here is the backtrace:

It segfaults when no argument is given, thus getopt() returns -1, the
`default' label isn't executed, usage() isn't executed either, and
later on it tries to access argv which corresponds to argv since
it was augmented by 1 in line 228: argv += optind; (optind is
initialized to 1)
I attach a patch that fixes it. It also contains a couple of
whitespace removals "since we are here".
