	* inferior.c (detach_inferior_command): Use get_number_or_range.
	(kill_inferior_command): Ditto.
	(remove_inferior_command): Ditto.
	(initialize_inferiors): Make command names plural.
	Update help strings.

2011-02-25  Michael Snyder  <msnyder@vmware.com>

	* gdb.texinfo (Inferiors and Programs): Update commands to show
	that they can accept multiple arguments.

2011-02-25  Michael Snyder  <msnyder@vmware.com>

	* gdb.multi/base.exp: Add test for remove-inferiors.
