svn commit: r352212 - head/sbin/nvmecontrol

[Warner Losh]

Author: imp
Date: Wed Sep 11 13:34:19 2019
New Revision: 352212
URL: https://svnweb.freebsd.org/changeset/base/352212

Log:
  Assume all the short args have optional args so allocate space for the
  ':'. It's slightly wasteful, but much easier (and the savings in bytes
  at runtime would be tiny, but the code to do it larger).
