How about the following? This swaps in perl in place of sed, which we can hopefully rely upon to work across platforms.

-------- 8< -------- Fix tests for broken sed on Leopard
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 use perl instead of sed, and at the same time add test cases for 1024 - 1 and 4096 - 1 as suggested by Junio.
