I think we're talking at cross-purposes. I'm not saying we should not fix
this problem. I'm saying that the proposed fix appears incomplete, which
means that (a) even if it solves your problem, it probably does not solve
related problems for other people; (b) since it's not clear why this
patch is apparently sufficient for you, I'd like to understand that in
some detail before deeming the problem solved; and (c) leaving instances
of the problematic code in our tree is just about guaranteed to mean
you'll have the same problem in future, when somebody either copies that
coding pattern into some new script or tweaks the way those existing
scripts are being used.
