Function has_path_prefix

utils.c:213–244

Compares if str has a specific path prefix. This differs from a regular prefix in two ways. First of all there may be multiple slashes separating the path elements, and secondly, if a prefix is matched that has to be en entire path element. For instance /a/prefix matches /a/prefix/foo/bar, but not /a/prefixfoo/bar. */
