Technically a separate request, since it's not "roll back the last change" but
"roll back to this version".

Separate request.

Although merged visually, you should still be able to "expand" the merged edits and view each one individually. The diff engine can't really handle that much, so I often make lots of smaller edits in a row that I know it will be able to display in a readable way. (Moving one paragraph to another position in its own edit, etc.)

See related discussion at https://en.wiktionary.org/wiki/Wiktionary:Grease_pit/2016/March#Consolidating_minor_edits_into_a_single_major_edit_in_an_entry.

This would require some thought regarding the implementation. For example, how would it interact with grouped changes (the "Group changes by page in recent changes and watchlist" option in preferences)? Would there be 2 levels of grouping in that case?

Quoting my comment from T35943, for convenience:

There's already a very nice script to accomplish this: https://en.wikipedia.org/wiki/User:Alex_Smotrov/histcomb.js -- however, it would be nice to have the functionality natively in MediaWiki.

One thing that should be kept in mind in implementing this, is that edits should only be combined if they are made in rapid succession (a few minutes apart at most). Otherwise, pages heavily edited by a single editor but across a longer timeframe, will have their edit histories unnecessarily obscured.
