Newer terminals (in particular gnome-terminal) understand special escape sequence for formatting clickable links. Let's support that to make our tool output more clickable where that's appropriate. For details see this: https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda The one big issue is that 'less' currently doesn't grok this, and doesn't ignore sequence like regular terminal implementations do if they don't support it. Hence for now, let's disable URL output if a pager is used. We should revisit that though as soon as less added support for it and enough time passed for it to enter various distributions.
