Comment(by bump):
Nicolas Thiery wrote the patch {{{trac_5794-reviewer-nt.patch}}}.
It is in the combinat patch queue. I took the liberty of uploading
it.
It addresses at least some of the ReST complaints.
I am changing the title back to [with patch, needs review] since
apart from the issue of the ReST formatting, the patches still
needs a technical review. The following remark is addressed
to whoever does the technical review. (Brant Jones was suggested.)
The patches as posted differ slightly from the versions in the combinat
queue.
The reason for the difference is that the meaning of the is_reducible
Cartan type attribute is changed by #4326. After #4326 (which preceed
these patches in the queue) the root system D2 is not reducible. See
http://groups.google.com/group/sage-combinat-
devel/msg/8b3569b4e2f2b7e1?hl=en
and thread for discussion. (Note: the {{{patch
cartan_type_temporary-1.patch}}}
mentioned in that message was qfolded shortly afterwards.)
