for outer loops

[pfitzseb]

Fixes #129.

outer is only a keyword in for outer loops, right?

I didn't even know that outer is ever a keyword.

Anyone else willing to review this?

[pfitzseb]

Well, it's 0.7 only, and I vaguely remember that there was a PR that added it. Can't really be bothered to look for it though, so tagging @ararslan again :)

Correct, though it can annotate any variable in the loop declaration, e.g.

i = j = 1
for outer i = 1:10, outer j = 3:4
    # ...
end

It is indeed 0.7 only, added in JuliaLang/julia#22659.

That case is surprisingly difficult to handle properly...

You may be able to take a look at how the Vim plugin does it; I think Carlo figured it out somehow.

Okay, this should be mostly fine now.
Only thing I'd like to improve is the end regex ((?<!,)(\\n)) -- it would be awesome if we could use something like (?<!,)(\\s*\\n), but that gives false positives for e.g. ", \n" because the \s* isn't greedy enough.

Alright, should really work now and handle most cases properly :)

Barring any objections I'll merge this tomorrow(-ish).
