Displaying a script correctly is very important for users of that script.
So, I agree that it is better that the fix for bug#21846 is included in
the next release.

Eli, what is the current rule for back-porting a patch in trunk to a
branch for the next release?

FYI, my change had one bug, but have recently fixed.
