>Description:
It would be useful to be able to display the details behind a boot menu
entry (or, indeed, the entire boot.cfg).  One might easily use this to
enter a custom command based on an existing menu option (but needing a
small change?).

A "dump" command with no options could display the entire boot.cfg file
(possibly passed through a pager/more if possible), while "dump <n>"
could display the command list associated with menu entry #n (pager is
less important here).
