Why? I think it is behaving properly - it fetches master branch from the server and merges it into 
local master branch, just as expected. I imagine that switching to master branch in all the 
subrepos before doing ./sync-all pull will be annoying. Perhaps a warning will be useful here, 
but error seems like too much.
