No reindexing indicator

[mtodd]

If I switch branches in github/github, switch to Atom, hit meta+t, and type the name of a file that is new in the branch, I will not see it until many seconds later. There is no indication that reindexing is happening, I just have to sit there knowing that reindexing is happening.

I would love it if there was at least some indication that the results is probably out of date and is being updated.
