Some will be replaced by newer versions.

Using array push

Instead of arr[arr.length] = x

someday.

This way all matches handle nests properly without special code.

If relative path doesn't work uses the absolute path to GitHub.

So they can fall back on absolute URL when necessary.

When dropped.
