When uploading new versions of raster graphics, we get text like: "Foo uploaded a new version of File:Bar.jpg:..." followed by whatever text a user chooses to insert as an edit summary. In the case of two separate JPEGs, that's probably the best you can do, but with vector graphics we could actually display differences *in* the SVG itself. It seems like this could be a very doable and useful function for spotting what the actual differences are between revisions of an SVG file.
This should be supported for all human-readable file formats (i.e. files that are not saved in a binary format). Example: https://commons.wikimedia.org/w/index.php?title=File:De_kaart_van_Yemo.png&withJS=MediaWiki:FileContentsByBot.js Diff: https://commons.wikimedia.org/w/index.php?title=File%3ADe_kaart_van_Yemo.png&diff=103195263&oldid=79481985

The need for this functionality has been identified again at the Oxford Wikimeet. Is there any liklihood of someone taking it forward any time soon?
(In reply to Chris McKenna from comment #3) I guess you could write a gadget or tool doing this; but I doubt a change in core will happen soon as too much would be involved. I've just written a user script on Commons that allows me in-page-editing of the SVG source code. https://commons.wikimedia.org/wiki/User:Rillke/SVGedit.js
