Maybe error-prone, but all is fine with the original code, right?

When you have "also" in a changelog commit, that usually means this
needs to be split out into a separate patch.  And that's the case here,
make the first patch of the series fix the problem.  Then do your
cleanups on later patches.

changing to a different string function does not fix anything.

It did not report that you need to replace a string function, right?

See, things got messy when you mixed in changes into one.  Please break
these up.
