New regression test for word splitting/search input parsing code.

2002-09-20  Not Zed  <NotZed@Ximian.com>

        * tests/misc/split.c: New regression test for word
        splitting/search input parsing code.

        * tests/folder/test9.c (main): Fix for filter_driver api change.

        * camel-search-private.c (camel_search_words_split): Handle "'s
        and \'s to escape characters.  For fat, lazy, slobs who dont like
        anything changing.
