commit 0e12beecd2d52a3540e0f93ddb031357a4912770

    Avoid unnecessary documentlanguage extra value
    
    * tp/Texinfo/XS/parsetexi/parser.c (wipe_global_info): Set
    global_documentlanguage to null rather than an empty string.
    This avoids a "documentlanguage" key being set on some @def*
    commands (like @defop) where there is no @documentlanguage directive
    in the document.  Report from Patrice.
