Comment 5 for bug 1175711

To make it easier for the next person, I've created a branch with Steven's patch:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1175711-tpac-renew-booking-items

Note also that it *mostly* contains formatting changes. The actual fix is limited to the 2 changed lines of Circulate.pm.
