Request: change of style for enumeration

[Jérémie Gaffarel]

It bugs me a little that, for the API docs of enumerations, the entire text appears to be inside quotation blocks.
For instance, in the picture below, it seems to me that the text beside the green lines should be out of the lighter box, at the same "level" as the "members:" text.

I do not know if there is a reason for this or if this is caused by a mistake in how we write the docstrings.
If this is unintentional, I don't know if you @geoffreygarrett can think of a fix for this?
