#81 make all sardana PEP8 compliant

[Carlos Pascual]

It can be done with autopep8, but tweaking it so that it does n not ugly things.

For example, I tried autopep8 with its default settings and observed that:

foo = bar - 1 # long comment that goes over col=79....

gets transformed into:

foo = bar -  \ 
          1 # long comment that goes over col=79....

and I would prefer something like:

foo = bar -  1 # here I write a very long 
               # comment that goes 
               # over col=79....

Well,
In fact you should avoid using inline comments:

It would be nice if instead autopep8 could transform all inline comments into a dedicated block comment above the code line

[Carlos Pascual]

What it says is you use them sparingly (do not use them to state obvious things).

I think they are justified in the following situations:

• non obvious statements (e.g. when you code something in a strange way to keep backwards compatibility with some old library...)
• marking TO-DOs or workarounds
• pointing to sources of recipes or to bug reports related with a certain part of the code

Unfortunately these cases are precisely the ones that tend to be long comments.

That said, I totally agree with Tiago that it would be nice if we find a way of converting those to comment blocks above the line
