--- Comment #1 from Ricordisamoa ricordisamoa@live.it --- This messy behavior originates in the MediaWiki API:
* "reason" is used to make actions that will be logged: [[mw:API:Delete#Parameters]], [[mw:API:Protect#Parameters]], etc. * "summary" is used when editing: [[mw:API:Edit#Parameters]] * "comment" is used when getting data (both revisions and logs): [[mw:API:Properties#Revisions:_Parameters]], [[mw:API:Logevents#Parameters]]
