By Per's comments, the incorrect TAOUP citation is now removed from
<https://srfi.schemers.org/srfi-176/srfi-176.html#_which_flag_to_choose>
and an explicit mention of -v, -version and --version has been added to
<https://srfi.schemers.org/srfi-176/srfi-176.html#_other_version_flags_and_multiple_commands>.
