History of Tags

[Stephan Doerfel]

In the history, the comparison of two versions of the set of tags is done on a string basis. It should however be done comparing the sets (e.g. ignoring the order of the tags in the database). E.g. this post http://history.biblicious.org/history/bibtex/d35a2f46d5e842ed1474724c0fc28492/sdo

yields this as the difference of the tags field: tags: MegaWurst asdf chrome imported kartoffel lecker newTag tac tic wer wurst superNewTaggOfDoom tac theReallyNewestTag tic wer wurst

(Here Bold font replaces the striked words). We see that the tags tac, tic, wer, and "wurst" are removed and added. This should however not be shown as a difference.
