doc: /* Define COMMAND as a prefix command. COMMAND should be a symbol.
A new sparse keymap is stored as COMMAND's function definition and its value.

as a function.
A new sparse keymap is stored as COMMAND's function definition and its
value.
This prepares COMMAND for use as a prefix key's binding.
If a second optional argument MAPVAR is given, it should be a symbol.
The map is then stored as MAPVAR's value instead of as COMMAND's
value; but COMMAND is still defined as a function.
The third optional argument NAME, if given, supplies a menu name
string for the map. This is required to use the keymap as a menu.
This function returns COMMAND. */)
