    I don't quite understand yet the need for having a new show command
    routine ... command.c (do_setshow_command) seems to be the one that
    handle the normal output of settings.  Also, show_language_command
    has similar setup as show_case_command ().  Do you have an example on
    the kind of behavior you'd like to see but not supported currently by
    this patch?

You added two commands:

  set case-sensitivity
  show case-sensitivity

And if the user types "show case-sensitivity", nothing will print
unless the sensitivity differs from that of the current language.  I
feel that if the user *ASKED* to be shown the case sensitivity, then
the user should be *SHOWN* the case sensitivity.  If the user
explicitily asks what it is, then it should not be silent.

So, you could have the command "show case-sensitivity" print something like:

  Case sensitivity is on.
  warning: current language, fortran, is case insensitive.

Where the first line is printed by a new function (to be called when
the user types "show case-sensitivity"), and the second line is
printed by the function (renamed) that currently implements "show
case-sensitivity".
