Hi,

could we mention an example value for the HTTP proxy setting?

When I use it it's never quite clear to me whether there's a slash at the end
or not, and what to do with https etc.

Currently it says "Please enter the HTTP proxy URL.  If you enter an empty
string, proxy usage will be disabled.".

I'd add a note: "(Example: http://10.0.0.1:8000)".

Also, if authentication is possible, maybe add that to the example.

What happens to https?  Will it go via the HTTP proxy?  Maybe mention that
there, too.
