True.  I found it easier to see from the way the patch was written
that this is a pure refactoring patch, though.  IOW, we may want to
do that on top as a further rewrite, but I am not sure if it makes
the result easier to reason about.  Such helper functions that are
file-scope static often help reading the logic flow of the program,
and compilers would inline them when it is more beneficial anyway.
