Hi all!
[ I'm not subscribed to this list so please CC me on your replies. ]
This patch adds an option to use either substring match, regular expression
match, or keywords search in the "make xconfig" Edit->Find dialog.
It also allows searching on the "help" field of the menus as well as
the "name" of the symbol.
This change involved adding the sym_generic_search function to the LKC, and
implementing sym_re_search using it.
Regards,
Shlomi Fish
