First working version of "pydent"

[Tim Peters]

[Jürgen Hermann]
> pydent is a tool that takes valid python source and indents it
> canonically (i.e. using no TABs and 4 spaces per indent level). While
> doing this, it tries to keep as much of the original formatting as
> possible, for example additional indenting on continued lines. It also
> removes trailing whitespace, including any whitespace on empty lines.

Were you aware of Tools/scripts/reindent.py in the std distribution?
