Minor language issue in documentation

[alexreg]

I just came across the following sentence.

In your IDE, you won’t see arguments that has to do with shell completion, because they are different in Click 7 and 8 (both supported by Cloup):

To fix the grammar, it should be be `that have to do with", though it still reads slightly awkwardly in my view. I think the following would be ideal.

In your IDE, you won’t see arguments relating to shell completion, since they are different in Click 7 and 8 (both supported by Cloup):

Of course, the choice is yours; I just wanted to point this out. :-)

Thanks for reporting :)

Oh, it looks like I had already fixed it with "have to do" but I'm not sure if this expression is so common in English, so I'll change it to "relating to" as you suggested.

@janluke Sounds good. (Yeah, while it is certainly an idiom, it is mainly used in casual speech, and sounds a bit odd in this context... very subtle, I admit.)
