largefiles: don't walk through all ignored files Problem: 'hg status' with largefiles enabled would walk through all the files that .hgignore said should be ignored. That made it slow if a lot of files were .hgignored or the cache was cold. It seems like there was a reason to this, but other improvements has rendered this unnecessary. Solution: .hgignore is now only ignored when that is requested (--ignore). This is a minimal 'stable' change. There is room for other improvement.

largefiles revert: update lfdirstate with result from first cleanliness check Largefiles revert do for some reason have two lfdirstates and lfdirstatestatus invocations in one function. The result from the first lfdirstate check was however not written back to the lfdirstate, and some files was thus checked twice.

largefiles status: update lfdirstate with result from cleanliness check Problem: 'hg status' kept checking largefiles with an unknown state until some other command wrote the updated dirstate. Solution: Add missing lfdirstate.write().

bundlerepo: don't return the peer without bundlerepo from getremotechanges Problem: getremotechanges would return the 'other' repo if nothing was incoming and there thus wasn't any bundle to base the repo on. The 'other' could be a http peer which only implement the functionality available over the http protocol. Transplant could thus fail with TypeError: argument of type 'httppeer' is not iterable Solution: Return the local repo instead of the remote peer if there is no reason to place a bundlerepo on top of the local repo.
