Purpose

   Handle components (partial functions) of a fit function

Examples

   FPOL 2
   FLAST/KEEP
   FPEAKS 7
   ...
   FLAST / DEL(1)

   Defines a polynomial as a "background" function (#1),
   then 7 gaussian peaks (#2) on top.
   Finally the polynomial function is removed.

Keep the last fit function, i.e. newly specified functions are
added, they don't replace the old function.

Delete all defined fit functions

If fct > 0: delete partial fit function number fct.
Remaining functions are renumbered.

List all partial fit function which contribute to the current fit function.

Suppress confirmation for delete.
