Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Wed Nov 27 15:28:40 2024 -0600

    [grn]: Align with modern groff conventions.
    
    * src/preproc/grn/hdb.cpp:
    * src/preproc/grn/main.cpp: Include system library headers before local
      ones.
    
    * src/preproc/grn/hgraph.cpp:
    * src/preproc/grn/main.cpp: Add Autoconf "<config.h>"-inclusion
      boilerplate to these translation units.
    
    * src/preproc/grn/hpoint.cpp: Drop unnecessary inclusion of
      "<stdlib.h>".
    
    Also clarify authorship history and public domain status in comment
    headers.
