minput_config_command - Configure the key sequence of an input method command.
, MSymbol command
Configure the key sequence of an input method command.
The minput_config_command() function assigns a list of key sequences keyseqlist
to the command command of the input method specified by language and name
If keyseqlist is a non-empty plist, it must be a list of key sequences, and each
key sequence must be a plist of symbols.
If keyseqlist is an empty plist, any configuration and customization of the
command are cancelled, and default key sequences become effective.
If keyseqlist is NULL, the configuration of the command is canceled, and the
original key sequences (what saved in per-user customization file, or the
default one) become effective.
In the latter two cases, command can be Mnil to make all the commands of the
input method the target of the operation.
If name is Mnil ,
this function configures the key assignment of a global
command, not that of a specific input method.
The configuration takes effect for input methods opened or re-opened later in
the current session. In order to make the configuration take effect for the
future session, it must be saved in a per-user customization file by the
function minput_save_config() .
If the operation was successful, this function returns 0,
otherwise returns -1. The operation fails in these cases:
- keyseqlist is not in a valid form.
- command is not available for the input method.
- language and name do not specify an existing input method.

MSymbol unicode = msymbol ('unicode');

should come some error handling code. */
/* Now CMD == ((start DESCRIPTION STATUS KEY-SEQUENCE ...) ...).
