svn commit: r308805 - stable/10/gnu/usr.bin/groff

[Ed Maste]

Author: emaste

New Revision: 308805
URL: https://svnweb.freebsd.org/changeset/base/308805

Log:
  MFC r306740, r307150: groff: use changelog date in man pages
  
  r306740:
  
  groff: use changelog date rather than file modification date in man pages
  
  The source checkout date is not particularly relevant, and this makes
  groff man pages build reproducibly.
  
  r307150:
  
  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.
