git/t/Git-SVN/Utils/join_paths.t
Michael G. Schwern ca475a61f8 git-svn: add join_paths() to safely concatenate paths
Otherwise you might wind up with things like...

    my $path1 = undef;
    my $path2 = 'foo';
    my $path = $path1 . '/' . $path2;

creating '/foo'.  Or this...

    my $path1 = 'foo/';
    my $path2 = 'bar';
    my $path = $path1 . '/' . $path2;

creating 'foo//bar'.

Could have used File::Spec, but I'm shying away from it due to SVN
1.7's pickiness about paths.  Felt it would be better to have our own
we can control completely.
