+I might have been wrong to introduce `typedlink(tag foo)`. It's not
+very user-friendly, and is more useful as a backend for other plugins
+that as a feature in its own right - any plugin introducing a link
+type will probably also want to have its own preprocessor directive
+to set that link type, and its own pagespec function to match it.
+I wonder whether to make a `typedlink` plugin that has the typedlink
+pagespec match function and a new `\[[!typedlink to="foo" type="bar"]]`
+though... --[[smcv]]

+----
+
+I am ready to merge this, but I noticed one problem -- since `match_tagged`
+now only matches pages with the tag linktype, a wiki will need to be
+rebuilt on upgrade in order to get the linktype of existing tags in it
+recorded. So there needs to be a NEWS item about this and
+the postinst modified to force the rebuild.

+Also, the ready branch adds `typedlink()` to [[ikiwiki/pagespec]],
+but you removed that feature as documented above.
