svn commit: r351157 - head/usr.sbin/config

[Warner Losh]

Author: imp
Date: Sat Aug 17 02:36:42 2019
New Revision: 351157
URL: https://svnweb.freebsd.org/changeset/base/351157

Log:
  Fix small bug in wrapping introduced in r325955.
  
  When local support was fixed, it introduced a minor bug in formatting. We don't
  increment the lpos by enouogh, so lines are a little too long. Adjust to be
  correct now with variable length srcprefix.
