Entry point for {{langx}}.
 
this function calls _lang_xx() to render non-English text. The {{lang-??}} templates have three positional paramters
but {{langx}} has four:
 
| 1 | 2 | 3 | 4
{{lang-xx |<text> |<transl> |<xlate> }}
{{langx |<tag> |<text> |<transl> |<xlate> }}
 
The calls to lang_xx_args_get() and _lang_xx() use 'Langx' as a flag for those functions to select the proper
positional parameters.
 
{{lang-??}} depends on the calling template to select 'inherit' or 'italic' to establish the default rendering.
 
{{langx}} can't do that. The initial version of {{langx}} relied on a list of language tags (inherit_t in ~/langx)
scraped from those {{lang-??}} templates that call lang_xx_inherit() to render text in upright font. Langx now
uses auto-italics code adapted from {{lang}} (doesn't support poem tags).
