I consider the automatic FTS_NOCHDIR a semi-bug that should not be
relied on. If FTS_NOCHDIR is set, fts(3) runs slower and is subject to
{PATH_MAX}. The latter would violate POSIX in various utilities.
I tried to allow FTS_LOGICAL without FTS_NOCHDIR a while ago, but while
it is conceptually possible, actually making it work is hard.
The open(".", O_RDONLY) can use O_SEARCH when it is added (for now,
O_EXEC works) so it only needs 'x' right not also 'r'.
