When removing indexing/slicing on exceptions some places were changed
inappropriately from ``e[0]`` to ``e.message`` instead of ``e.args[0]``.  The
reason it needs to be the last option is the dichotomy of 'message' and 'args':
'message' can be the empty string but args[0] can have a value if more than one
argument was passed.
