See http://gcc.gnu.org/onlinedocs/gfortran/Extensions-to-namelist.html for the
description of the ? and =? extension.

Actually, there are two bugs:

a) With "?", no attempt is made to read the next item. That's a bug due to
Jerry's patch for PR 47154 (http://gcc.gnu.org/r168502). Here, '?' was falling
through to a "goto find_nml_name;" - but no longer after "case EOF:" was added.

b) With "?", there is no output. Seemingly, a regression due to Janne's patch
for PR 25561 (http://gcc.gnu.org/r135373). Here, a "if (!p)" got lost.
