[TxMt] "test" in Language editor not working with "inline markdown"

[Charilaos Skiadas]

I noticed the following while playing with the markdown bundle. Seems  
to me like a bug when changing a language that is included in the  
current language for a document.

1) Open an empty document, write some stuff (including some inline  
markdown like emphasis) and select markdown as a language.
2) Make changes to the inline markdown language, press format and  
test. They are not reflected in the text.
3) Opening a new file, copying the text over, and making the language  
in the new file markdown reflects the changes. The original file  
still does not show any difference.
4) Changing the language of the original file to LaTeX, and then back  
to markdown doesn't fix it either.
5) Changing the language of the original file to Inline markdown, and  
then back to markdown still leaves it bad.
