This module implements the {{multitrans}} template.
Original author: Benwing2, based on an idea from Rua.
Significantly reworked by Theknightwho.
The idea is to reduce the memory usage of large translation tables by
computing the whole table at once instead of through several separate calls.
The entire text of the translation table should be passed as follows:
{{multitrans|data=
* Abkhaz: {{tt|ab|аиқәаҵәа}}
* Acehnese: {{tt|ace|itam}}
* Afrikaans: {{tt+|af|swart}}
* Albanian: {{tt+|sq|zi}}
* Amharic: {{tt|am|ጥቁር}}
* Arabic: {{tt+|ar|أَسْوَد|m}}, {{tt|ar|سَوْدَاء|f}}, {{tt|ar|سُود|p}}
*: Moroccan Arabic: {{tt|ary|كحال|tr=kḥāl}}
* Armenian: {{tt|hy|սև}}
* Aromanian: {{tt|rup|negru}}, {{tt+|rup|laiu}}
* Asháninka: {{tt|cni|cheenkari}}, {{tt|cni|kisaari}}
* Assamese: {{tt|as|ক’লা}}, {{tt|as|কুলা}} {{qualifier|Central}}
* Asturian: {{tt|ast|ñegru}}, {{tt|ast|negru}}, {{tt|ast|prietu}}
* Atikamekw: {{tt|atj|makatewaw}}
* Avar: {{tt|av|чӏегӏера}}
* Aymara: {{tt|ay|ch’iyara}}
* Azerbaijani: {{tt+|az|qara}}
[etc.]
}}
That is, take the original text and add a 't' to the beginning of translation
templates:
{{t|...}} -> {{tt|...}}
{{t+|...}} -> {{tt+|...}}
{{t-check|...}} -> {{tt-check|...}}
{{t+check|...}} -> {{tt+check|...}}
The {{tt*|...}} templates are pass-throughs, so that e.g.
{{tt|ary|كحال|tr=kḥāl}} generates the literal text "{{t|ary|كحال|tr=kḥāl}}".
This is then parsed by the template parser to extract the arguments, which
are then passed into the same code that underlyingly implements the regular
translation templates. Because all of this happens inside a single module
invocation instead of lots of separate ones, it's much faster and more
memory-efficient.
