safety fix for glob's vla usage: disallow patterns longer than PATH_MAX this actually inadvertently disallows some valid patterns with redundant / or * characters, but it's better than allowing unbounded vla allocation. eventually i'll write code to move the pattern to the stack and eliminate redundancy to ensure that it fits in PATH_MAX at the beginning of glob. this would also allow it to be modified in place for passing to fnmatch rather than copied at each level of recursion.
