The wiki doesn't mention it, but I think the rule should only apply when
there's a space before the parens.  Otherwise, we have a problem with
all the tests that call functions, and don't explicitly specify a test
name, like:

  gdb_test "p function(1)" " = 1"

We have many such cases, C tests, Python tests, etc:

 $ grep "[a-z](.*)$" testsuite/gdb.sum  | wc -l
 1174

I don't think it's worth it, or even a good idea to try to
come up with different test names for all of these.  In cases like
these, I think it's generally possible to avoid the space before
the parens.  So IMO, we should clarify the rule instead
(and the buildbot testresult diffing accordingly, if necessary).
