In the past, the "comment" field of "File history" sections of image description pages was cut when exceeding a certain size: it is cut in the middle of the word "contains" as you cannot read further than "This record cont" on File:Andrew Carnegie, William Howard Taft, Elihu Root and Cardinal Gibbons, with others posed in Pan American Union Building, Washington, D.C.jpg (uploaded in 2008).
On File:Physical damage, blast effect, Hiroshima, 1946-03-13 ~ 1946-04-08, 342-USAF-11071.ogv (uploaded on 6 October 2011) however, the whole content of the description page's edit field was copied there without any cut.
On File:Alba Iulia National Museum of the Union 2011 - Late Bronze Age Tools and Weapons.JPG (uploaded today) the comment field is empty. Why?
Are those bugs or features? What is the expected behaviour of the comment field ? By the way, do we really need the "()" brackets ?
