Running a specific BDD-style section does not work

[mimon]

Describe the bug Given the following example:

SCENARIO("pizza") {
  GIVEN("dough") {
    WHEN("applying") {
      THEN("cheese") {
        CHECK(false);
      }
    }
  }
}

Then running a specific section name $ test *pizza* -c "dough" does not run any assertions on my machine (when it should):

Filters: *pizza*
===============================================================================
test cases: 1 | 1 passed
assertions: - none -

Expected behavior The assertion should be executed and output something like:

Filters: *pizza*

The problem here is that due to an implementation detail, the spaces before "given" are part of the section name when you need to filter. This is already being worked upon in the FilterWS branch, for now you can work around it by providing the name like this:

$ ./a.out *pizza* -c "    Given: dough"
Filters: *pizza*

Okey. Got it. It works when adding the spaces and the prefix. Thanks.

I'll keep this open until we merge the fix into master.
