Good old git blame lol! Not only can you determine when the change was made and where, it’s trivial to look up the author of the commit: https://github.com/iputils/iputils/commit/562e0d570d93cfcfdebab1215a2f04efa64a24f8
To be fair, the author’s first language may not be English…
Is anyone interested in submitting a pull request? Looks like Github contributions are accepted.
I think descriptive and useful error messages are OK to report as enhancements. They don’t have to be functional bugs.
