Add brackets to the allowed path chars

[sztanpet]

brackets are widely used in paths, so add them

http://bgp.he.net/search?search[search]=vortex.data.microsoft.com&commit=Search was not matched for example

[sztanpet]

this does not make sure the brackets are well formed

I was worried about parenthesis because they are used often, like in markdown links. Hence why I made xurls only accept them if they matched in the url.

Can you think of any pattern that would make urls be surrounded by brackets? Somethink like [http://foo.bar] that would need to match http://foo.bar instead of http://foo.bar].

[sztanpet]

maybe in bbcode? otherwise not really

[mvdan]

I'll merge this and fix the "surrounded by brachets" edge case separately.

Thanks for your help!

[sztanpet]

thank you!
brackets might be an issue with ipv6 addresses too, since they are only valid when they are surrounded by them

@sztanpet done.
