python scripts: pep8ize codebase

This was done with the aid of the pep8 script, available by running
`easy_install pep8`.

It may be worth making this part of ./check, but that will require
putting pep8 into the development tools stratum.
This should be easy, given pep8 has no external dependencies.

     Some build systems are well known: autotools, for example.
     Others are purely manual: there's a set of commands to run that
     are specific for that project, and (almost) no other project uses them.
     The Linux kernel would be an example of that.
