[fortran, patch] Remove parentheses and comma in error message.

[Tobias Burnus <burnus at net-b dot de>]

Hello,

This patch removes the "(   ,  )" in the error message function
gfc_trans_runtime_check().
This is used by the array checks (bounding error, strides) and for the 
format-label errors; it also will be used by the substring check (review
pending).

This change was suggested by Steve; I also prefer it to the current version.

Old/current error message (example):
---------------
Fortran runtime error: Array reference out of bounds for array 'a',
upper bound of dimension 1 exceeded (in file 'string2.f90' at line 6)
---------------

New/proposed error message (example):
---------------
Fortran runtime error: Array reference out of bounds for array 'a',
upper bound of dimension 1 exceeded in file 'string2.f90' at line 6
---------------

All the testcases, I found, use something like
"upper bound of dimension 1 exceeded.*at line 6" and are thus not
affected by this patch.

Tobias
