* found felipe's segfault in util.c and fixed the segfault (3 tests fail due to odd behavior of . and .. on this machine) * fixed serious flaws in the setting/resetting of is_data - now it works properly. Assume all new PharData are tar-based, and allow passing Phar::ZIP to PharData constructor to override this * fix broken earlier commit, introduced segfault that broke 20 tests here
