Pylint, at least our current version (still 1.4.4 as some more recent
versions are apparently much slower), may choke on some imports on the
first validation since Zope was started, only to later succeed. Hypothesis
is that it fails to analyse some imported modules, leaving empty shells
behind in some cache, making a second test avoid the error.
Here is one such error:

The last navigation step is intended to pull an anonymous-accessible
document. ERP5Site is too magic a document to have a representative
behaviour.

These are useless, git complain about them and they cause unnecessary diffs when having editor configured to automatically remove spaces at end of lines, so let's do a big commit to remove them all at once
