I did some tests for unbalanced curly braces in the gfortran testsuite
and got quite some output, see attached patch.

additionally,
- corrected "dg-do  run" issues (double space)

I think some of the test cases might to it on purpose: "dg-do run"causes the test case to run only once while "dg-do run" runs multipletimes with different options. If the testcase is supposed to test therun-time library, calling it multiple times is pointless. Admittedly,using two spaces is an ugly hack, but creating a "dg-do run-single" isdifficult. Those test cases are rather quick, hence, running multipletimes, keeping the double space version or doing the latter but adding acomment all work.

- dg-flags should be dg-options
- string adjustments needed after fixing curly braces


Thanks for the patches! Committed as http://gcc.gnu.org/r199636
