[WIP] Support configurable URL schemes in git-link

[Copilot]

• Analyze the problem statement and understand current code structure
• Locate the git-link--web-host function and understand its usage
• Identify how web-host values are used in handler functions
• Write comprehensive tests for the new functionality
• Implement scheme detection logic in git-link--web-host function
• Create helper function git-link--format-url for URL construction
• Update git-link-github handler to support custom schemes
• Update remaining handler functions (GitLab, Bitbucket, etc.)
• Test the implementation with various scenarios
• Verify all existing tests still pass

This pull request was created as a result of the following prompt from Copilot chat.

Update the git-link--web-host function to allow customizable URL schemes for git-link commands. Currently, the handler functions (git-link, git-link-commit, and git-link-homepage) retrieve a hostname, which is then passed to a handler, and the hostname is derived from an entry in git-link-web-host-alist. This alist is in the form (GIT-HOST-REGEXP . WEB-HOST) where WEB-HOST is usually hardcoded to use the https scheme. The desired change is to allow users to specify a scheme within the WEB-HOST value. In the git-link--web-host function, determine if the WEB-HOST value already has a URL scheme (for example, it begins with a pattern like "https:" or "http:"). If it does not, modify the WEB-HOST value by prepending "https:" to it. This way, users can configure alternative schemes by specifying them directly in the git-link-web-host-alist. The change should be implemented in a single commit or squashed into one commit before opening the pull request.

@copilot all values (functions) in git-link-remote-alist, git-link-commit-remote-alist, and git-link-homepage-remote-alist must be updated like this, to support a hostname with a prefix.

Also git-link--format-url does not look necessary since all hosts returned by git-link--web-host will have a scheme.

[Copilot]

Updated all handler functions in git-link-remote-alist, git-link-commit-remote-alist, and git-link-homepage-remote-alist to support scheme-enabled hostnames. Also removed the unnecessary git-link--format-url function as requested. Commit 995b624

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https (dns block)
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list
