I fixed repo links on Upstream projects page to not link to git.wikimedia.org. But it seems http://git.wikimedia.org/tree/at-ease.git has no equivalent in Diffusion.
If and when someone fixes this, update https://www.mediawiki.org/wiki/Module:Callsigns
@demon @20after4 would you mind looking at it?
Any repo created after I mass-created them awhile back is likely to be missing. Individual tasks to import missing ones are...less than useful...as I prefer to do them in batches.
