Subject: [BUG] t7004 (master) busted on Leopard
Message-ID: <17E3F66C-4644-4B64-817C-88062727A2D9@wincent.com>

Commit 4d8b1dc850 added a couple of tests to t7004, and my testing  
reveals that this one has been broken on Leopard since then:

* FAIL 83: message in editor has initial comment
GIT_EDITOR=cat git tag -a initial-comment > actual || true &&
test $(sed -n "/^\(#\|\$\)/p" actual | wc -l) -gt 0

(Not sure whether this affects other platforms, or versions of Mac OS  
X prior to Leopard, as I only have one machine here.)

The problem is the version of sed that ships with Leopard fails to  
match the initial comment with this syntax:

sed -n "/^\(#\|\$\)/p" actual

An alternative that works is:

sed -n "/^[#\$]/p" actual

Can someone with knowledge of sed compatibility across multiple  
platforms suggest an alternative which will work on a wider range of  
systems?

Cheers,
Wincent
