git describe --contains 6e6de3dee51a
v5.3-rc1~38^2~6

I'm a bit torn about this situation. Reverting 6e6de3dee51a would be the
right thing to do, but without it, it still leaves the issue reported
by Prarit Bhargava. We need a way to resolve the issue on stable and
then your optimizations can be applied on top.

Prarit Bhargava, please review Petry's work and see if you can come up
with a sensible way to address this for stable.
