Subject: [PATCH] Menuconfig search changes
Date: Thu, 02 Sep 2004 12:43:48 +0300	[thread overview]
Message-ID: <4136EB54.6060705@il.aduva.com> (raw)

Modified the search to go over the properties attached to a symbol (like 
Roman suggessted).
Added regex support to help narrow down the searches.
Displaying the parameter's dependencies (nothing fency - simply using 
expr_fprint).
Added a 'show_file' helper function.
(This patch should be applied after applying Andrew's modifications)
Thanks.
