commit 7ee15ff4c05182acc5e7f219273fade439f4712e
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Wed Nov 27 14:18:16 2024 -0600

    [hpftodit]: Fix code style nits.
    
    * src/utils/hpftodit/hpftodit.cpp:
    * src/utils/hpftodit/hpuni.cpp: Align with modern groff conventions.
      Add Autoconf "<config.h>"-inclusion boilerplate to these translation
      units.  Include system library headers before local ones.
    
    * src/utils/hpftodit/hpftodit.cpp: Use standard symbol `EXIT_SUCCESS`
      instead of zero literal.  Drop inclusion of "<ctype.h>"; none of its
      symbols (`is*()`) are directly used.
