    doc/groff.texi: Document CSTR #54 erratum.
    
    * doc/groff.texi (Operators in Conditionals): Document CSTR #54 erratum
      regarding output-equivalence conditional operator [that is:
        .if '\\$1'arg'
      "oh yeah, THAT thing" --GBR].
    
    Fixes <https://savannah.gnu.org/bugs/?60836>.
    
    [Formatting of submitted text altered slightly to use TeX quotation
    marks and remove a paragraph break.  You can also blame me for the use
    of the term "comparand", an irruption of my exuberance as a frustrated
    mathematician and logophiliac.  --GBR]
