Warner Losh 23f24377b1 awk: Merge 20210729 from One True Awk upstream (0592de4a)
July 27, 2021:
	As per IEEE Std 1003.1-2008, -F "str" is now consistent with
	-v FS="str" when str is null. Thanks to Warner Losh.

July 24, 2021:
	Fix readrec's definition of a record. This fixes an issue
	with NetBSD's RS regular expression support that can cause
	an infinite read loop. Thanks to Miguel Pineiro Jr.

	Fix regular expression RS ^-anchoring. RS ^-anchoring needs to
	know if it is reading the first record of a file. This change
	restores a missing line that was overlooked when porting NetBSD's
	RS regex functionality. Thanks to Miguel Pineiro Jr.

	Fix size computation in replace_repeat() for special case
	REPEAT_WITH_Q. Thanks to Todd C. Miller.

Also, included the tests from upstream, though they aren't yet connected
to the tree.
