Log:
Enable truncation attribute in Z39.50 queries to be left out entirely

Per https://bugs.launchpad.net/evergreen/+bug/702695, some Z39.50
servers hate the truncation attribute (@attr 5=anything) and always
return 0 hits.

This gives you the ability to specify a negative value for the
truncation attribute and thereby prevent the truncation attribute
from being included in the Z39.50 query for a given server.
