I think this is a documentation issue. Since scipy uses pytest under the 
hood to actually run the tests, any extra arguments after `--` are 
passed to pytest, so you should be able to use `python runtest.py -- -k 
"*ttest_rel*' which will use pytest's regex test chooser. At least that 
is the way it works on numpy ...
