fails to update indirect buffers in other frames

[SawyerGardner]

indirect buffers are not updated unless it is visible in the current frame, even if it is visible in other frames. I'm pretty sure you can fix this by adding t or maybe 'visible to (window-list) in git-gutter:update-indirect-buffers so it checks all frames instead of just the active one.

edit: I did some testing and my proposed solution has no effect. I cant seem to find where the problem is located.
