[PATCH] Fix git-remote for ActiveState Perl

[Alex Riesen <raa.lkml@gmail.com>]

For reason unknown a package in ActiveState Perl 5.8.7 must implement
READLINE method differently for scalar and array context. The code
tested to work for more sane and recent version of perl (5.8.8 shipped
with Ubuntu), so maybe it was always a requirement.

Without this only the first remote can be used if you are unlucky
enough to use that perl. There are probably more breakages, as only
first line of a file/stream can be read. Not many use Git.pm on
Windows and ActiveState Perl, so it went unnoticed for long time.
