Subject: [PATCH] Tpac: paging support for serials issues (non-MFHD)

When you click "issues held," when using the
opac.fully_compressed_serial_holdings org unit setting so that you get a
list of individual issuances you can potentially place holds on, now
there's some basic forward/back paging with a default page size of 10.

Thought this was done a while ago, but I must have been crazy.
