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.
