It seems a bit fragile to put semantics in having totally consistent 
translation of DEPRECATED. (And even more so to base the test on having 
it translated in the Swedish translation.)

BUT we do already check for the translated string elsewhere in help.py, 
so this is just making it consistent and not making it worse.

Another observation is that it is inconsistent whether the magic string 

It seems like a better solution would be to only check for the magic 
word in the untranslated string - and either pass that or a flag around 
where it is needed. Alternatively, have a flag when defining an option 
and then add add the DEPRECATED string when relevant when the option 
description is shown to the user.
