[seqfan] Primes with increasing digits

This sequence is wrong. After a(10) = 8929, the next term should be 
8969. Inserting that, the next term is 12347, but again after 89189, 
the next term should be 89237, then 89269, 89293, 456791, 456923, and 
we are now on a completely different trajectory.

These terms were computed semi-manually (making repeated calls to 
PARI's nextprime function), so I'm not 100% confident of them - but I 
am sure that the terms out there now are incorrect. Any volunteers to 
actually program the thing?
