SH_WORD_SPLIT (-y) <K> <S>
Causes field splitting to be performed on unquoted parameter
expansions. Note that this option has nothing to do with word
splitting. (See *note Parameter Expansion::.)
Perform word splitting using the rules for SH_WORD_SPLIT during the
evaluation of SPEC, but regardless of whether the parameter appears
in double quotes; if the '=' is doubled, turn it off. This forces
parameter expansions to be split into separate words before
substitution, using IFS as a delimiter. This is done by default in
most other shells.
Note that splitting is applied to WORD in the assignment forms of
SPEC _before_ the assignment to NAME is performed. This affects
the result of array assignments with the A flag.
It's unclear to me what is meant by "Note that this option has
nothing to do with word splitting" here.
It seems the SH_WORD_SPLIT description makes a distinction
between "field splitting" and "word splitting", but then again
throughout the manual (including the $=spec description above),
"word splitting" and "field splitting" are used interchangeably
to refer to the same thing.
Was the intended meaning something like: "Note that it does not
affect how the shell delimits tokens" or something like that?
