+
+Code inside a link, which is the only pair code takes:
+[`code span`](./z.md) and [a`b`c](./w.md).
+
+All four at once, over a boundary space:
+**q**~~** r **~~**s**
+
+A struck run whose edge is a tab:
+x~~	t	~~y
+
+A struck run that covers exactly one whole link, and one that covers two:
+[~~all of it~~](./whole.md) and [~~a~~](./a.md)~~ and ~~[~~b~~](./b.md).
