Then I am not sure why it wasn't matching.  However it wasn't, and
moving into post-transfer accommodation it did!

I don't care what follows the _d_, so "~^ja:.*_d_" is the shortest
possible match.  In practice, there is always at least one more
character, so "~^ja:.*_d_.*" is equivalent, but I don't see I gain
anything by matching more.
