* Partial TIP 27 rollback. Following routines

        restored to return (char *): Tcl_DStringAppend,
        Tcl_DStringAppendElement, Tcl_JoinPath, Tcl_TranslateFileName,
        Tcl_ExternalToUtfDString, Tcl_UtfToExternalDString,
        Tcl_UniCharToUtfDString, Tcl_GetCwd, Tcl_WinTCharToUtf.  Also
        restored Tcl_WinUtfToTChar to return (TCHAR *) and
        Tcl_UtfToUniCharDString to return (Tcl_UniChar *).  Modified
        some callers.  This change recognizes that Tcl_DStrings are
        de-facto white-box objects.

	* generic/tclCmdMZ.c: corrected use of C++-style comment.
