It doesn't seem clear to the user just what changed on many lines of
http://en.wikipedia.org/w/index.php?title=Allen_Swift&action=historysub…
E.g.,
|-+----------------------------------------------------------+-+----------------------------------------------------------|
|-|| ALTERNATIVE NAMES = |+|| ALTERNATIVE NAMES =
|
|-+----------------------------------------------------------+-+----------------------------------------------------------|
|-|| SHORT DESCRIPTION = |+|| SHORT DESCRIPTION =
|
|-+----------------------------------------------------------+-+----------------------------------------------------------|
Maybe it is removing or adding invisible characters or something.
True I could use action=raw to see what was really in there, but to the
average user it looks like one big head scratcher.
