I saw the paragraph in XRAT-6 C.1.4 "Change History" saying
it covered the changes since Issue 5 and the following paragraph
"also lists the changes since the ISO POSIX-2: 1993 standard".
So, I was looking for the rationale from the initial standard,
rather than the subsequent changes, thinking that there might
be more contemporaneous details.

Skimming through XCU-6, I saw where -v and -V were additions so some
earlier spec, but missed the mention of the Eighth Edition "builtin".
I reckon that "command" was a reasonable change from "builtin",
even though it makes searching for it rather troublesome. 8-)

Thanks for the extra info, Sven, and especially for your web pages.
They are a wonderful resource.

Best Regards,
