Is your feature request related to a problem? Please describe.

In general, when copying the URL, for many - it might make more sense to share the permanent link to avoid any surprises later. Sharing just the file URL might just become invalid/incorrect if any commit (later) changes the corresponding file/piece of code.

Being able to share the permanent link would help solve this problem.

Describe the solution you'd like

Design: (user-facing) Having an option with what='permalink' or something similar would help.

The URL pattern, for at least GitHub would look like:

...
permalink = "/blob/{commit_hash}/{file}#L{line_start}-L{lne_end},
...

Implementation (dev-facing): commit_hash would store the output of system({ "git", "-C", cwd, "rev-parse", "HEAD" }, "Failed to get current commit")[1]. We'll probably need something similar for bitbucket/others (I've not tested them yet, can do once this is approved).

Describe alternatives you've considered

I tried passing the commit to the URL patterns from the user side, but then realised that commit variable does not really store the commit has value. Was my bad, I'm not aware of any other alternatives with this plugin.

Additional context

I'll be happy to help create a PR if this feature request sounds reasonable to the maintainers. Thanks for the amazing work!
