The str:gsub returns either A|B froma 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 labelif str was wrapped in wikilink markup. Presumably, this is because without wikimarkup in str, there is no matchin the initial gsub, the replacement function l doesn't get called.
