1410f938aa read: discard IFS delimiters before the last token
Do this only when splitting on IFS characters which usually contains
whitespace characters --- read --delimiter is unchanged; it still
consumes no more than one delimiter per variable. This seems better,
because it allows arbitrary delimiters in the last field.

Fixes #6406

86133b0a2b Add read --tokenize
This splits a string into variables according to the shell's
tokenization rules, considering quoting, escaping etc.

This runs an automatic `unescape` on the string so it's presented like
it would be passed to the command. E.g.

    printf '%s\n' a\ b

returns the tokens

printf
%s\n
a b

It might be useful to add another mode "--tokenize-raw" that doesn't
do that, but this seems to be the more useful of the two.

Fixes #3823.
