[PATCH 4/7] Add join_paths() to safely concatenate paths.

From: "Michael G. Schwern" 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'.
