[Bug fortran/31812] New: Better message than "syntax error" when truncating long lines

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

gfortran silently trunkates lines which gives syntax errors. Especially in free
format, the truncation is usually not intended. (In fixed format is sometimes
is.)

Other compiles print a warning (such as g95, all options; syntax error
afterwards), give an error (such as NAG f95) or (silently) accept longer lines
(ifort, all options).

gfortran prints a warning, but only with -Wall not with -pedantic -std=f95.

Real-world example:
http://gcc.gnu.org/ml/fortran/2007-05/msg00042.html

Message:

"," name=",1H",A,1H",">",A,"</i>")',ADVANCE="Yes") blank(1:inden),tag,str(1
                                                                          1
Error: Syntax error in argument list at (1)
