Test Milestone

The following should produce the same result: ⟨Column ?⟩ ⟨Column ?⟩ ⟨Column ?⟩ ⟨Column ?⟩ ⟨Column ?⟩ ⟨Column ?⟩ ⟨Column ?⟩

Use of milestone/@n: ⟨Column A⟩ ⟨Column A⟩ ⟨Page A⟩ ⟨A⟩ ⟨Column A–32 hello–world⟩ ⟨Page A–32 hello–world⟩ ⟨A–32 hello–world⟩

Trailing label after a milestone: ⟨Column ?: My label⟩ ⟨Column ?: My label⟩ ⟨Page ?⟩ ⟨?⟩ ⟨Column 1: My label⟩ ⟨Column 1: My label⟩ ⟨Page 1⟩ ⟨1⟩

Use of fw; after a pagelike milestone or pb, is incorporated into the page break; otherwise it is treated separately. ⟨Column ?⟩ ⟨Page ?⟩⟨top: Hello⟩ ⟨Column ?⟩ ⟨?⟩

fw with/without @n (for now we don’t display the @n) and with/without contents ⟨Page ?⟩⟨top: ⟩ ⟨Page ?⟩⟨top: ⟩ ⟨Page ?⟩⟨top: ⟩ ⟨Page ?⟩⟨top: Hello⟩ ⟨Page ?⟩⟨top: Hello⟩ ⟨Page ?⟩⟨top: Hello⟩

fw with a valid @place: ⟨Page ?⟩⟨bottom left: Hello⟩ ⟨Page ?⟩⟨bottom right: Hello⟩ ⟨Page ?⟩⟨bottom: Hello⟩ ⟨Page ?⟩⟨left: Hello⟩ ⟨Page ?⟩⟨right: Hello⟩ ⟨Page ?⟩⟨top: Hello⟩ ⟨Page ?⟩⟨top left: Hello⟩ ⟨Page ?⟩⟨top right: Hello⟩

fw with an invalid @place: ⟨Page ?⟩⟨top: Hello⟩ ⟨Page ?⟩⟨whatever: Hello⟩

Using several consecutive fw elements is possible: ⟨Page ?⟩⟨top: Hello⟩⟨bottom: Hello⟩

Use of both label and fw after milestones. The label must immediately follow the milestone. ⟨Page ?⟩

Space handling. If the milestone has @break=no, all spaces around it are removed. But if not, we modify the text in such a way that there is one space (and only one) around each milestone. Except that, if the milestone appears at the very beginning of a block, we don’t add a space before it.
