This fixes all instances of " \t" in the code base. Most common case
seems to be after a "where" line; probably vim copied the two space layout
of that line.
Done as a background task while listening to episode 2 of the Type Theory
podcast.
This will be used by the remote-daemon to quickly tell when changes have
been pushed from some other repository into a ssh remote.
Adjusted the remote-daemon protocol to communicate changed shas, rather
than git branch refs. This way, it can easily check if a sha is new.
