--[=[
DISPLAY_HANDLERS is a list of one or more functions that provide special handling for multipart tags. Each function
takes formerly a single argument (the multipart tag), now temporarily two arguments (the multipart tag and the join
strategy, which can be nil to use the default), and should either return the formatted display text or nil to check the
next handler. If no handlers apply, there is a default handler that appropriately formats most multipart tags.
CAT_FUNCTIONS is a map from function names to functions of a single argument, as described in [[Module:form of/cats]].
There are two types of functions: condition handlers (which return true or false) and spec handlers (which return a
specification, as described in [[Module:form of/cats]]). We need to put the functions here rather than in
[[Module:form of/cats]] because that module is loaded using mw.loadData(), which can't directly handle functions.
