Syntax:  SHOW LANGUAGE language_name_wild

  Displays the characteristics of the specified language(s).

  If you specify a language name, LSE displays all the attributes
  associated with that language.  If you specify a wildcard language
  name, LSE displays brief information about each matching language.

  You can navigate through the language list using Ctrl/F (forward) and
  Ctrl/B (reverse).  Ctrl/E (expand) lets you display full information
  on the indicated language.  The COLLAPSE command reverts back to the
  brief display.
