Change "\," to just "," in function signatures. This is easier to maintain,
works better with LaTeX2HTML, and allows some simplification of the python.sty
macros.

Apart from the \code{Pickler} and \code{Unpickler} classes, the
module defines the following functions, and an exception:
-\begin{funcdesc}{dump}{object\, file\optional{, bin}}
+\begin{funcdesc}{dump}{object, file\optional{, bin}}
Write a pickled representation of \var{obect} to the open file object
\var{file}. This is equivalent to
\code{Pickler(\var{file}, \var{bin}).dump(\var{object})}.
