Markdown error in help mode

General Usage
1

When I tried to check the function hypot via the help mode, I got the following Markdown error regardless of using Atom/Juno or REPL via Terminal. Also, this occurs on Mac, Windows, and Linux machines. How can we resolve this problem? Thanks!

help?> hypot
search: hypot CholeskyPivoted

  hypot(x, y)


  Compute the hypotenuse \sqrt{x^2+y^2} avoiding overflow and underflow.

You might need to provide more details about your Julia version, since this is what I get for both my source-build and a binary download on linux (v. 1.0.01 and 1.0, respectively):

help?> hypot

  hypot(x, y)

@tim.holy; thank you very much for your reply. I’m using Julia v1.0.1 downloaded from the official Julia site for my three platforms (Mac, Windows, Linux). I didn’t build it from the source.

As the stacktrace suggest this is an issue with OhMyREPL.

Thanks a lot! I just posted the issue at the OhMyREPL GitHub site.

Should be fixed on master.
