Content of the Milestone page is not converted.
During a test migration from Trac to Readmine it occured that the text which is on the milestone page in trac is converted into the Description text and not as supplemental Wiki page (Wiki page) which can be attached to a Version. (Revision 1900 of trunk).
I would suggest to simple convert the text on the milestone page into a supplemental wiki page (same name as the milestone) and all formattings etc. will work.

The time stamp of the created wiki pages for the milestones are not correct, but this can only be fixed in relationship with Issue #1949, where we get the correct time stamp of the milestone (milestone.completed).
An other part is the user name of the wiki pages for the milestones, which is currently hard coded (not good style). I think we should use the author name of the milestone.
