svn commit: r307150 - head/gnu/usr.bin/groff

[Ed Maste]

Author: emaste
Date: Wed Oct 12 15:49:20 2016
New Revision: 307150
URL: https://svnweb.freebsd.org/changeset/base/307150

Log:
  Avoid using 'head' in generating groff doc date
  
  It may not be available in certain cross build cases.
  
  Note that this is a slight change in functionality, in that now only the
  first line of the source ChangeLog file is processed. This is acceptable
  as groff will be retired and we won't encounter a possibly-different
  ChangeLog format.
