Remove prefix $ and > from manual

[styfle]

These are not literal characters so when you copy/paste, it fails.

LGTM

There's a bunch of others on the page, is there a reason they weren't also removed?

Edit: I like the $ in the examples actually.

@hayd I guess I didn't read that far yet. I was just trying to install.

It looks like some of them include responses too so maybe thats why that prefix with $.

Ideally there would be css to include this prefix so copy/paste wouldn't pick it up.
