This "Fixes" didn't make much sense. You're not really fixing a
previous commit here. Rather you're fixing an autobuilder issue, so
I've added a reference to the autobuilder issue being fixed instead.

Added a comment above this indicating that it can be dropped when
bumping to bash 5.3.

Applied to master with those fixes. Thanks again!
