Subject: [PATCH] Bug 27461: Right pad with default elements for too short 008s

Note that we treat the elements 18-34 as one block of elements,
since its subdivision may vary.
E.g. if you pass 24 characters to the form, it will use the first
18 chars (until the last complete element) and pad with default
elements from position 18-39.

Test plan:
[1] Go to addbiblio. Make sure that 008 is connected to the plugin.
[2] Backspace field 008 a bit, click on the plugin button.
[3] Verify that the last elements come from the default.
[4] Repeat for a few different lengths.
