Changes stylesheet so that where a change entry refers to multiple issues or PRs, the links to each one are rendered correctly. (For an example, see "Lookup Expressions" in XQuery.)

For some reason this has pulled in other commits.

Generally speaking, the approach that I find works is:

1. Check out your master branch
2. Make sure you're in a clean state; stash outstanding edits or save them in a different local branch
3. Pull the master branch from the "upstream" repo (qt4cg)
4. Rebase your local master with upstream
5. Checkout -b the branch you want to use for the PR you're planning
6. Edit, commit, and push that branch
7. Make a PR from it

What you want to avoid doing is the checkout -b step from an existing PR branch or a master branch that's not up-to-date with the upstream repo.

That's a pretty accurate description of (a) what I try to do, and (b) what goes wrong if you forget one of the steps.
