    * font.c (font_unparse_xlfd): Don't blindly alloca long strings. · c21721cc

    Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
    fits in int, when using sprintf.  Use single snprintf to count
    length of string rather than counting it via multiple sprintfs;
    that's simpler and more reliable.
    (APPEND_SPRINTF): New macro.
    (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
    (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
    sprintf, in case result does not fit in int.
