Remove duplicate $digest()

[gitMbar]

Seems like the same event was added twice on accident. Perhaps something else was meant in place of the second $digest() but as it stands it is confusing.

I'm not sure why it's talking about "digest" and "events" in the same sentence at all. Those are probably supposed to be talking about broadcast and emit rather than digest.

@caitp - actually all my commit changed was the link.

[caitp]

Actually I'm wrong, that comment goes back a lot further than that commit :x -- yeah, that line has changed a few times, but the intent of the line never seems to have been questioned, it goes back a few years

Here we go, looks like it was this: 42062da --- I guess we used to have $flush and $digest. Yeah this looks right, just remove the second $digest and it makes sense.

[caitp]

Anyways yeah, lgtm --- just surprised it took so long to be corrected :p I'm still not sure why we're calling it an "event", but I guess it works

[gitMbar]

caitp - should I close this and open a new pull request with $flush and $digest?

[caitp]

no, $flush was removed years ago --- I'm merging this, just fixing the trailing whitespace first

[gitMbar]

Cool, thanks
