Fix per-directory exclude handing for "git add"
In "dir_struct", each exclusion element in the exclusion stack records a base string (pointer to the beginning with length) so that we can tell where it came from, but this pointer is just pointing at the parameter that is given by the caller to the push_exclude_per_directory() function. While read_directory_recursive() runs, calls to excluded() makes use the data in the exclusion elements, including this base string. The caller of read_directory_recursive() is not supposed to free the buffer it gave to push_exclude_per_directory() earlier, until it returns. The test case Bruce Stephens gave in the mailing list discussion was simplified and added to the t3700 test. Signed-off-by: Junio C Hamano <gitster@pobox.com>
