occurrences of any of the characters in tt($IFS). Note this step, too,
takes place at all levels of a nested substitution.

item(tt(10.) em(Re-Evaluation))(
item(tt(10.) em(Uniqueness))(
If the result is an array and the `tt((u))' flag was present, duplicate
elements are removed from the array.
)
item(tt(11.) em(Ordering))(
If the result is still an array and one of the `tt((o))' or `tt((O))' flags
was present, the array is reordered.
)
item(tt(12.) em(Re-Evaluation))(
Any `tt((e))' flag is applied to the value, forcing it to be re-examined
for new parameter substitutions, but also for command and arithmetic
substitutions.

item(tt(13.) em(Padding))(
Any padding of the value by the `tt(LPAR()l.)var(fill)tt(.RPAR())' or
`tt(LPAR()r.)var(fill)tt(.RPAR())' flags is applied.

item(tt(14.) em(Semantic Joining))(
In contexts where expansion semantics requires a single word to
result, all words are rejoined with the first character of tt(IFS)
between. So in `tt(${LPAR()P)tt(RPAR()${LPAR()f)tt(RPAR()lines}})'
