Bump, can this be merged?

[mcabbott]

BTW, using this seems to cause JuliaDiff/ChainRules.jl#598 . I've no idea why, though.

[martinholters]

I have no idea what's going on, but JuliaDiff/ChainRules.jl#598 (comment) says:

This wasn't an issue with Compat either, but with an older version of JuliaFormatter in my startup.jl!

And I failed to reproduce the problem. If someone can come up with a reproducer, I'm willing to look at it, but I doubt it's Compat's fault.

[mcabbott]

Thanks for looking. I can't reproduce it either, but just wondered if you (or anyone) had ever seen something like this. I see nothing wrong with what either package is doing.
