+Bugs:

+* \[[!inline pages="..." trail=yes]] currently tries to work out
+ what pages are in the trail, and their order, at scan time. That
+ won't work, because matching a pagespec at scan time is
+ unreliable - pages we want might not have been scanned yet! I
+ haven't worked out a solution for this. I think
+ \[[!inline pagenames="..." trail=yes]] would be safe, though.
