Hi maintainer,

I'll send the patch to fix the "directory" command problem.

When the directory command is issued without any parameters,
the source search path is supposed to be initialized.
But it doesn't work under "set confirm off".


ChangeLog:

2008-03-06  Hidetaka Takano <hidetaka.takano@glb.toshiba.co.jp>

	* source.c (directory_command): modify the determination of
	condition of terminal "from_tty".

Best regard.
