When creating an analytical record from scratch and filling the 773
field with marc21_linking_section.pl plugin, the information put
in field 773 is very basic, incomplete, sometimes buggy ($9, $0).
Test plan
=========
1. Configure a MARC bibliographic framework: enable essential
subfields in 773: 7, a, t, b, d, g, k, x, z, w (check the Editor
checkbox), put them in this order, and chose plugin
marc21_linking_section.pl for 773 $t.
2. Start creating a new record and go to 773 $t. Activate the plugin
to find the a record to become the host record (perform a search
for 'Linux kernel development'). Note the content of the 773
field.
3. Apply the patch, restart plack etc.
4. Repeat p. 2.-3. See that the generated 773 field contains now much
more information, including 773 $7.
Additionally, commented code has been removed and check/variable
initialization added to get rid of warnings in log.
