	libmisc/shell/internal.h, libmisc/shell/shell.c,
	libmisc/shell/shell.h, libmisc/shell/shellconfig.h: Command set
	processing now separated from main command loop. Addition of user
	commands and aliases tested. Monitor registration now explicit.
	* libmisc/shell/shell_cmdset.c, libmisc/shell/shell_makeargs.c,
