Broken ignore

[kans]

This is a strange bug to reproduce - the gist is that atom doesn't ignore some very simple rules that it should. Further testing revealed this only happens for me when the path is /floobits/ag and not ``~/ag`. The repo in question is ggreer/the_silver_searcher.

d = atom.project.getDirectories()[0]
Directory {symlink: false, didRemoveSubscription: function, willAddSubscription: function, emitter: Emitter, subscriptionCounts: Object…}
d.getPath()
"/floobits/ag"
r = atom.project.repositories[0]
GitRepository {emitter: Emitter, subscriptions: CompositeDisposable, repo: Repository, statuses: Object, upstream: Object…}
r.getPath()
"/floobits/ag/.git"
r.isPathIgnored('compile')
false

(master) $ cd /floobits/ag
(master) $ git check-ignore compile
compile

A few other plan text ignores exhibit the same behavior. Am I missing something?
