--[=[
GORUNTU_HALLEDİCİLERİ 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.

KAT_FONKSİYONLARI is a map from function names to functions of a single argument,
as described in ]. There are two types of functions:
condition handlers (which return true or false) and spec handlers (which
return a specification, as described in ]). We need to
put the functions here rather than in ] because that
module is loaded using mw.loadData(), which can't directly handle functions.
