keywords.pl broken by conditional & alternation lines in tests

[dfandrich]

Several tests use %if clauses in the <errorcode> section of tests (e.g. 178) and others use a list of <errorcode> values (e.g. 405). These are not handled properly and result in (presumably) incorrect statistical output, at least. These warnings are shown when perl warnings are enabled:

Argument "%if hyper\n" isn't numeric in addition (+) at keywords.pl line 75.
Argument "%if hyper\n" isn't numeric in addition (+) at keywords.pl line 75.
Argument "%if hyper\n" isn't numeric in addition (+) at keywords.pl line 75.

Oh right. Yeah, anything that parses the test files really need to parse the preprocessed output version rather than the source version if they cannot handle the preprocess instructions.

To make keywords.pl work again, I suppose we need to enhance runtests.pl in a way so that we can invoke it to only generate the log/testNUM file (possibly on stdout) and then have keywords.pl use that...
