99ebf78686a9 patch 8.1.0914: code related to findfile() is spread out Bram Moolenaar <Bram@vim.org> parents: diff changeset	29 * First you create yourself a search context by calling vim_findfile_init().

99ebf78686a9 patch 8.1.0914: code related to findfile() is spread out Bram Moolenaar <Bram@vim.org> parents: diff changeset	37 * with some new parameters. Don't forget to pass your old search context to
