Normalized a few cases of whitespace in function declarations.

Found them using::

  find . -name '*.py' | while read i ; do grep 'def[^(]*( ' $i /dev/null ; done
  find . -name '*.py' | while read i ; do grep ' ):' $i /dev/null ; done

(I was doing this all over my own code anyway, because I'd been using spaces in
all defs, so I thought I'd make a run on the Python code as well.  If you need
to do such fixes in your own code, you can use xx-rename or parenregu.el within
emacs.)
