Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already used the three-arg form of open() which was introduced in 5.6.1, but t/t9700/test.pl explicitly depended on 5.6.2.
However git-add--interactive.pl has been failing on the 5.6 line since it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open syntax:
sub run_cmd_pipe {
my $fh = undef;
open($fh, '-|', @_) or die;
return <$fh>;
}Which when executed dies on "Can't use an undefined value as filehandle reference". Several of our tests also fail on 5.6 (even more when compiled with NO_PERL_MAKEMAKER=1):
t2016-checkout-patch.sh
t3904-stash-patch.sh
t3701-add-interactive.sh
t7105-reset-patch.sh
t7501-commit.sh
t9700-perl-git.shOur code is bitrotting on 5.6 with no-one interested in fixing it, and pinning us to such an ancient release of Perl is keeping us from using useful features introduced in the 5.8 release.
The 5.6 series is now over 10 years old, and the 5.6.2 maintenance release almost 7. 5.8 on the other hand is more than 8 years old.
All the modern Unix-like operating systems have now upgraded to it or a later version, and 5.8 packages are available for old IRIX, AIX Solaris and Tru64 systems.

A follow-up to the discussion in "Let's bump the minimum Perl version to 5.8". I took the liberty of adding Tor and Randal's Acked-by to the patch based on their comments in the thread. Which is why this is an RFC, if they're OK with it it can be applied.
