testsuite oddities

[Manfred Schwarb]

Hi,

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

old summary:
# of expected passes		44390
# of expected failures		52
# of unsupported tests		79

new summary:
# of expected passes            44498
# of expected failures          52
# of unsupported tests          79

could someone please check and commit?

Cheers,
Manfred
