Closes #646.
This patch tries to find the right URL for HEAD when in detached HEAD state. If there's a matching tag on HEAD (e.g.
git checkout v2.2
) it will use it, otherwise, SHA. This is my attempt to fix the issue without fully understanding the codebase, so maybe I'm doing something incredibly wrong here and if there's a better way to handle this, feel free to close this PR. Actually I couldn't figure out what^\d\=$
is supposed to match, but I noticed that it matches empty string in detached HEAD state.
