	differs slightly from ksh93:
	- omit trailing field in a3zna, a7ina (unquoted $@ expansion)
	- has extra middle fields in b5ins, b7ina (IFS_NWS unquoted expansion)
	differs slightly from bash:
	- omit leading field in a5ins, a7ina (IFS_NWS unquoted expansion)
	differs slightly from zsh:
	- differs in assignment, not expansion; probably zsh bug
