    Strip '+' from tag file name for configure option
    
    * macros/mm-doc.m4 (MM_ARG_WITH_TAGFILE_DOC): Correct the regular
    expression used to strip off the suffix of the tag file name in order
    to produce a suitable name for the configure option.  Specifically,
    properly handle the case of both '++' and '-d.d' occuring together.
