(OBS): Put version.o first, so Makefile rebuild happens early. * command.h: Publicize prototype for not_just_help_class_command. * command.c: Remove proto. * maint.c: Mark "mt" as an abbrev, to avoid duplicated help output. Move "maint info" from class info to class maintenance, and improve text. * infrun.c: Move "stop" to class_obscure, and give it a function so it will not be seen as a global help topic. FIXME, it should be possible to set these attributes independently. * core.c (core_command): Make nicer error message for no core support.
