Gets the display text from a wikilink like [[A|B]] or [[B]] gives B
The str:gsub() returns either A|B froma [[A|B]] or B from [[B]] or B from B (no wikilink markup).
In l(), l:gsub() removes the link and pipe (if they exist); the second :gsub() trims white space from the label
if str was wrapped in wikilink markup. Presumably, this is because without wikimarkup in str, there is no match
in the initial gsub, the replacement function l() doesn't get called.

Makes a wikilink; when both link and display text is provided, returns a wikilink in the form [[L|D]]; if only
link is provided, returns a wikilink in the form [[L]]; if neither are provided or link is omitted, returns an
empty string.
