Warn on displayable error?

[JoshCheek]

I've been doing nothing b/c it can display the error, but if you have a lot of code in the window, you might wind up missing this, so maybe it should warn on displayable errors, too?

eg here:

atom-seeing-is-believing/lib/seeing-is-believing.coffee

Line 75 in 63e35c4

if code == 2 # nondisplayable error

Really, it depends on how it winds up working for other people in practice, which isn't something I necessarily know :/

Alternatively, It could hi light the line or something. Atom probably has some builtin way to draw attention to a line. To do that, the editor would have to know what line had the error, could add a flag to receive diagnostic on stderr.
