When we add a new name, up all of the cache limits, because we're probably

2002-03-25  Not Zed  <NotZed@Ximian.com>

        * camel-text-index.c (text_index_add_name): When we add a new
        name, up all of the cache limits, because we're probably going to
        be adding more.
        (text_index_sync): Drop the cache limits back down again, we dont
        need them when looking words up.

        ** MERGE camel_index branch.

        * camel-text-index.[ch]: Added files i forgot to add (eep nearly
        lost all this work!)

        * camel-block-file.c (sync_nolock): Fix an infinite loop in syncing.
