SYNOPSIS
int|string <name>(string cmd)

DESCRIPTION
After set_modify_command(mob) was called for an interactive
object iob, all commands for that user will be passed to
mob-><name>(), and the return will then be checked for
actions. The actual name of the lfun to call is specified
by the H_MODIFY_COMMAND_FNAME hook - traditionally it's
'modify_command'.

If the result is a string, it is the new command to execute
instead of the given one. Note that it is not possible to
make several commands from one this way!
If the result is a non-zero number, the given command is to
be ignored. In case of the closure/lfun setting this may
mean that the closure/lfun already executed it.
If the result is 0, the originally given command is to be
used.

HISTORY
In 3.2.1@109 the name of the lfun to call must be specified
using the H_MODIFY_COMMAND_FNAME driver hook.
