Return a formatted block of contents of the format suitable for Notes and Queries.
Basically, this is just a list of em-dash-separated links, which are given one per line:
Link -> [[NaQ/Series S/Volume V/Number NNN/Link]]
Link\Display -> [[NaQ/Series S/Volume V/Number NNN/Link|Display]]
Link, 123 -> [[NaQ/Series S/Volume V/Number NNN/Link]], 123
Series, Volume and Number are params #1, 2, 3
Parm 4 is an optional prefix which will be unlinked. Often "NOTES:" or similar.
Formatting is not applied - this is done in the template.
