    groff_char(7): Revise `\[ul]` table entry.
    
    Refer to it as the "underrule", as CSTR #54 (1976) did (in spite of the
    dubious mnemonic).  Since it is font-invariant and forms corners with
    \[rn] and \[br], it may be misleading to suggest an identity with the
    orinary underscore glyph, `_`, U+005F.
    
    Continues commit 885489e3e,6 May 2021.
