Incorrect parsing/rendering in VersionAdded (and maybe other) directives #386

Open

Description

(this is probably known but wanted to document anyway)

VersionAdded (and potentially VersionChanged and Deprecated) are incorrectly parsed: the arguments of the directive (for example the version number for the change mentioned) are included in the directive title. When running papyri as an ipython extension this creates and error. For regular html rendering or textual/rich rendering this passes silently.
