    man pages: Protect env variables from hyphenation.
    
        * src/devices/grotty/grotty.1.man:
        * src/preproc/preconv/preconv.1.man:
        * src/roff/nroff/nroff.1.man:
        * src/utils/lkbib/lkbib.1.man:
        Suppress hyphenation of environment variables in running prose.
        Not necessary in examples (if .EX/.EE are used), when the
        variables are .TP or .TQ paragraph tags, or when groff wouldn't
        hyphenate them anyway.
    
        (In exciting trivia, none of:
                GROFF_BIN_PATH
                GROFF_FONT_PATH
                GROFF_NO_SGR
                GROFF_TMAC_PATH
                GROPDF_NOSLIDE
                HOME
                LANG
                LC_ALL
                LC_CTYPE
                MANOPT
                PAGER
                PATH
                SHOW_PROGRESS
                SOURCE_DATE_EPOCH
                TEMP
                TMP
        have hyphenation points according to groff.)
