[Quilt-dev] [patch 3/8]

[gary]

Mac OS X 10.4 (I use 10.4.2) doesn't ship a tac command, and the darwin
ports install of coreutils installs its version as gtac.

This patch falls back to using a short perl one-liner when the system
does not have a tac command.  gtac isn't searched for since using perl
obviates the requirement to `port install coreutils'.
