MagicLink doesn't link user/.github#num correctly

[woodruffw]

Description

Hi there, thanks for this extension set! I'm a very happy user.

I noticed what I think is a MagicLink bug in zizmor's documentation, appearing with woodruffw/zizmor#415: it looks like user/.github#num doesn't appear to recognize user/.github as the user/repo slug, and instead sees it as {default_user}/github#num.

For example, nextcloud/.github#477 is included here and gets linked incorrectly to https://github.com/woodruffw/github/issues/477, instead of https://github.com/nextcloud/.github/issues/477.

Some additional details here: woodruffw/zizmor#415

Minimal Reproduction

1. Use user/.github#num as a MagicLink
2. Observe that the link is to {default_user}/github#num instead of user/.github#num

Version(s) & System Info

Yes, this is a bug. We were including an unnecessary check that the repo has a word boundary at the start, but since repos can start with ., this caused the . to be invalid when at the start of the repo name. This could cause the user name part, along with the . to be discarded and treated like a repo internal to the default user.

Anyway, the fix is pretty easy and I should have one up sometime soon.

Awesome, thanks for confirming! Please let me know if there's anything else I can do.
