Subject: [RFA] Remove command_line_handler_continuation.
To: gdb-patches@sources.redhat.com
X-KMail-Transport: CodeSourcery
X-KMail-Identity: 901867920

	[gdb]
	* top.c (command_line_handler_continuation): Remove.
	(execute_command): Do not install the above.

	[gdb/doc]
	* gdb.texinfo (Maintenance Commands): Clarify that "maint time"
	will not report the time of commands that run the target.
