"No difference" is not useful to show to users; the diff page for moves in particular is probably pretty common. Instead, show something nice by way of meta-data (currently the log is written in hard-coded in the acting user/content lang)?
"No difference" is correct because a move or protect produce a null revision which points to the same text blob than the previous revision. The summary is in content language as the reason or most of other summarys by users.
(In reply to Umherirrender from comment #1) > "No difference" is correct because a move or protect produce a null revision I am aware of how MediaWiki works. :-) It's insanely stupid UX, however.
