Florian's new patches move a line of code in one, and immediately remove
it in the second, just to satisfy a BZ.  I doubt the readers of the BZ
care about anything beyond "it was fixed" 99% of the time.

I don't feel too strongly about this because the code is the same in the
end, but it seems like extra work with a weak justification.  These are
the types of requirements that may put off a first-time contributor.
Obviously this doesn't apply to Florian ;-)
