Just for the record, I figured it out, I made things unnecessarily
complicated. Here is the working line:
complete --command conky-colors --no-files --long-option 'lang' --arguments
'bg de en et fr it pl pt ru es uk' --description 'Set language'
The clue was that no '=' is necessary in the long option 'lang', and the
--arguments had to be in the same complete command where the option is
defined and fish beautifully prompts the missing '=' with all the arguments.
