Yes likely (without checking). It's also likely a 1-liner fix,
and perhaps caused by the previous patch to add a trailing '\0'
(the same code is traversed).

The --Va code is also multi-threaded, leading to (iirc) about
a 1.5x speedup, and the behavior may change depending on how
rpm is built.

This report is different than the original, which
claimed that '5' was being displayed for all files (including
directories which indicates some seriously different breakage
if affecting all files, not just %config files.

It most definitely is _NOT_ an intended change in behavior
from rpm4 -> rpm5.
