All subrepos pushed when pushing repo
Created originally on Bitbucket by Zoltán Lehóczky
When you push a repo with subrepos you'll see such operation for every subrepo (regardless of them being changed or not):
pushing subrepo Path\To\Subrepo to https://hg.subrepo.com
searching for changes
no changes found
This makes pushing repos with many subrepos horribly slow.
A very-very long time ago this was the case, then it was change not to push all subrepos and everybody was happy. Then this issue was re-introduced in TortoiseHg 3.3 I think and still existing in 3.3.2.
