Subject: [PATCH] Fix test failure due to broken sed on Leopard
Message-ID: <1197990675-41698-1-git-send-email-win@wincent.com>

```
The newly-added common-tail-optimization test fails on Leopard because
the broken sed implementation bails with a spurious "unterminated
substitute pattern" error because of the length of one of the
arguments.

So halve the size of the argument (to 1024 - 1, down from the previous
2048 - 1) to get the test passing again.
