feature: prompt_pwd function support hyperlinks

Unfortunately I haven't managed to make tmux 3.4 display hyperlinks, can you share steps to reproduce?

@krobelus Simply add this config to .tmux.conf file to enable the hyperlinks feature.

set -ga terminal-features "*:hyperlinks"

systemd also outputs it always if stdout is a terminal

That's good news, then.

I'm extremely careful to add any feature that terminals have to support because there are a ton of extremely bad terminals that people insist on using, but if we already have a big thing that uses a particular feature unconditionally it appears to be supported enough. If some obscure terminal has issues we can probably just tell people that better terminals are available for free.

The question is whether this feature helps a real use case.

Tbh I personally haven't ever wanted this. I see now that the terminal would mark hyperlinks, which may be annoying. It will also typically open them in your graphical file manager, which I don't tend to really do.

Fish already gives the terminal the PWD via OSC-7, so your terminal already has the information and could give you a "go to directory" button or open a new tab in the same directory.

Detecting if a given terminal supports a sequence is always a massive pain - unfortunately terminal developers tend to focus on adding features to their own terminal instead of making compatibility easy.

So I'm going to say that we don't want to do this. You can add it to your own prompt by doing something like

printf '\e]8;;file://%s\e\\\%s\e]8;;\e\\' $(string escape --style=url -- $PWD) $(prompt_pwd)

wherever you print the PWD.

We don't need to probe for this feature, we can use it unconditionally because terminals that don't support this feature will ignore it. systemd also outputs it always if stdout is a terminal (they have a compile-time option to turn it off but that's mainly for pagers that don't support this).

The question is whether this feature helps a real use case.
Since tmux by default open new windows in the directory of the session (not the current window's directory), I think it could improve the OOTB experience.

I agree that prompt_pwd doesn't have a strong case. Worth trying sure but not sure if it's a good default.

I think much more useful and less objectionable is to add hyperlinks to valid paths which are already underlined.
Possibly also to commands that resolve to scripts, like the new Ctrl-O binding.

(actually we'd need to add a couple of exceptions for known-broken terminals; we can copy what gcc does (see info gcc | less +/At.this.time))
