--- Comment #4 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
I knew this looked familiar. We did it on purpose. From list_read.c:
/* A trailing space is required, we give a little latitude here, 10.9.1. */
c = next_char (dtp);
if (!is_separator(c) && c != '!')
{
unget_char (dtp, c);
goto find_nml_name;
}
I think we allowed sepraators for some old legacy stuff. I will make
adjustments.
