"2024 July 12 - GNU nano 8.1 "de dag van de bitterkoekjespudding"

    The idiom nano filename:linenumber is understood only when
    the option --colonparsing (or 'set colonparsing') is used.
    Modern bindings are not activated when nano's invocation name
    starts with "e", as it jars with Debian's alternatives system.
    New bindable function 'cycle' first centers the current row,
    then moves it to the top of the viewport, then to the bottom.
    It is bound by default to ^L.
    Option --listsyntaxes/-z lists the names of available syntaxes."
