commit b611ff59a189d062a689635bb81245dd77b6a381
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Fri Dec 25 21:27:59 2020 +1100

    [docs]: Call texi2dvi with FORCE_SOURCE_DATE=1.
    
    * doc/doc.am (.texi.dvi): Call texi2dvi with FORCE_SOURCE_DATE=1 in the
      environment, avoiding an embedded timestamp in the generated groff.dvi
      file, which frustrated reproducible builds.  Thanks to Werner Lemberg
      for the suggestion.
