Todd Zullinger d13a73e383 perl: bump the required Perl version to 5.8.1 from 5.8.0
The following commit will make use of a Getopt::Long feature which is
only present in Perl >= 5.8.1.  Document that as the minimum version we
support.

Many of our Perl scripts will continue to run with 5.8.0 but this change
allows us to adjust them as needed without breaking any promises to our
users.

The Perl requirement was last changed in d48b284183 (perl: bump the
required Perl version to 5.8 from 5.6.[21], 2010-09-24).  At that time,
5.8.0 was 8 years old.  It is now over 21 years old.

=head1 NAME
Git::I18N - Perl interface to Git's Gettext localizations
=head1 SYNOPSIS
use Git::I18N;
print __("Welcome to Git!\n");
printf __("The following error occurred: %s\n"), $error;
printf __n("committed %d file\n", "committed %d files\n", $files), $files;
=head1 DESCRIPTION
Git's internal Perl interface to gettext via L<Locale::Messages>. If
L<Locale::Messages> can't be loaded (it's not a core module) we
provide stub passthrough fallbacks.
This is a distilled interface to gettext, see C<info '(gettext)Perl'>
for the full interface. This module implements only a small part of
it.
=head1 FUNCTIONS
=head2 __($)
L<Locale::Messages>'s gettext function if all goes well, otherwise our
passthrough fallback function.
=head2 __n($$$)
L<Locale::Messages>'s ngettext function or passthrough fallback function.
=head2 N__($)
No-operation that only returns its argument. Use this if you want xgettext to
extract the text to the pot template but do not want to trigger retrival of the
translation at run time.
