Should we support Perl 5.6?

Hi,

I just had a failure when pulling, because since a few days (to be exact, 
since commit 1cb30387, git-fmt-merge-msg uses a syntax which is not 
understood by Perl 5.6.

It is this:

	open $fh, '-|', 'git-symbolic-ref', 'HEAD' or die "$!";

I know that there was already some discussion on this list, but I don't 
remember if we decided on leaving 5.6 behind or not.

Somebody remembers?

Ciao,
Dscho
