read_command_lines should reset control_level

[Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>]

Since control_level is a static variable it is impossible for all callers
of read_command_lines to reset it.


1999-02-02  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* top.c (read_command_lines): Reset control_level.
	(define_command): Don't do it here.
