do no-op post_commit test in wrapper
This speeds up web commits by 1/4th of a second or so, since perl does not have to start up for the post commit hook. perl's locking is completly FuBar, since it's impossible to tell what perl flock() really does, and thus difficult to write code in other languages that interoperates with perl's locking. (Let alone interoperating with existing fcntl locking from perl...) In this particular case, I think I was able to find a way to avoid the insanity, mostly. The C code does a true flock(2), and if perl is using an incompatable lock method that does not use the same locking primative at the kernel level, then the C code's test will fail, and it will go ahead and run the perl code. Then the perl code's test will test the right thing. On Debian, at least lately, perl's flock() does a true flock(2), so the optimisation does work.
