I plan to commit the following as simple.
The issue was a value was being modified on a short namelist read. After
tthe first read gives the correct EOF, a second read would give the
error but modify the variable.
diff --git a/libgfortran/io/unit.c b/libgfortran/io/unit.c

Hi Jerry,
I've made a small compiler survey how they behave on namelist read
from an internal unit when:

"&stuff" // testchar // " n = 666/"
2.) the input spans 2 lines split after the testchar
3.) same as 2.) but first line right-adjusted

Hi Jerry, Steve,
I think I have to pour a little water into the wine.
The patch fixes the reported issue only for a comma after
the namelist name, but we still accept a few other illegal
