a. Fixed a bug that assigned a value to the variable name supplied as an

This doesn't seem like it's fixed

$ bash -c 'echo $BASH_VERSION; unset foo; for i in 1 2 3; do wait -p
foo; declare -p foo; done'
declare -- foo="0"
declare -- foo="1638738736"
declare -- foo="1638738960"

`wait -p' doesn't really do anything useful when the `-n' option isn't
supplied. But we can make sure to leave it unset if there aren't any jobs.

e. Here-document parsing now handles $'...' and $"..." quoting when reading the
    here-document body.

And I don't think this is very useful with aposthropes remaining

$ cat <<X

$'\n' is identical to

Here-document bodies are parsed as if they are within double quotes, and
single quotes are not special within double quotes.
