ਸੋਧੋWhen a template returns a string starting with colon, as this subtemplate is sometimes ordinarily expected to do, the wiki platform prefixes a linebreak to it. Functions within a Wikilisp expression are not subject to this limitation since the entire Wikilisp expression is within a single template call; the result from this template can therefore be renormalized by Wikilisp function trim
, stripping off the prefixed linebreak, but must then be further processed within the Wikilisp expression to avoid re-prefixing by the wiki platform.
