backport: re PR libfortran/56786 (Namelist read fails with designators containing embedded spaces)

2013-04-28  Jerry DeLisle  <jvdelisle@gcc.gnu.org>

	Backport from mainline:

	PR libfortran/56786
	* io/list_read.c (nml_parse_qualifier): Remove spurious next_char call
	when checking for EOF. Use error return mechanism when EOF detected.
	Do not return FAILURE unless parse_err_msg and parse_err_msg_size have
	been set. Use hit_eof.
	(nml_get_obj_data): Likewise use the correct error mechanism.
	* io/transfer.c (hit_eof): Do not set AFTER_ENDFILE if in namelist
	mode.

	Backport from trunk:

	PR fortran/56786
	* gfortran.dg/namelist_81.f90:  New test.
