Solution: Use a ":help" command to create the help window. (closes #9475, closes #9458, closes #9472)

" Provide 'PrintVer' command to print the interface versions.

func s:print_ver(lang, ...)
  if has(a:lang)
    exec a:lang join(a:000)
  else
    echo 'N/A'
  endif
  echo ''
endfunc

command -nargs=+ PrintVer call <SID>print_ver(<f-args>)
