RFR: 2466: Cut down list of other commits from 10 to 3 [v2]

[Magnus Ihse Bursie]

> Skara prints a list of other commits that has been integrated before a PR is automatically rebased. I think the idea was to put transparency to the rebasing process, but in actuality it only adds noise.
> 
> I think it could be removed entirely (in general, I think the Skara bot messages are *waaaay* to chatty), but as a start, it the list could be shortened radically. I chose 3 as the lowest number that is still a "crowd".

Magnus Ihse Bursie has updated the pull request incrementally with one additional commit since the last revision:
