the script when running a ShTest with an external or internal shell. This bug is caused by use of the ``map`` function in Python 3 which returns an iterable (rather than a list in Python 2). After the iterable is exhausted it won't return any more output and consequently when ``_runShTest()`` tries to access the ``script`` which has already been iterated over it is empty. Converting to a list immediatley after calling ``map()`` fixes this. This fixes the ``tests/shtest-format.py`` test when running under Python3 which was previously failing. llvm-svn: 253556
