[groff] 48/72: [pre-grohtml]: Update usage message.

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit b484d4f0ddba9683bddaf6af89c3cc711fcbcc7d
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sun Oct 23 11:48:51 2022 -0500

    [pre-grohtml]: Update usage message.
    
    * src/preproc/html/pre-html.cpp (usage): Update usage message.  Document
      --version and --help options.
    
    Also downcase metasyntactic variable names; there's no need to shout
    them when they're separated from option flag letters by space.  Also
    remove brackets from "troff-command" and "troff-argument" operands;
    these are effectively mandatory.
