When you say "optimize" have you observed any actual benefits of the
patch - be that smaller binary, faster execution time, etc?
If there are - mentioned them in the commit message. Otherwise, it
doesn't optimise anything.

A while back, I've suggested something similar [1] mostly for cosmetic
purposes - doubt there's much benefits beyond that.
