Upstream commit 1:

[PARSER] Recognise here-doc delimiters terminated by EOF
Previously dash required a <newline> character to be present in order for
a here-document delimiter to be detected. Allowing EOF in the absence of
a <newline> to play the same purpose allows some intuitive scripts to
succeed. POSIX seems to be silence on this so this should be OK.
Test case:
eval 'cat <<- NOT
test
NOT'
echo OK
Old result:
test
NOTOK
New result:
test
OK

Bash doesn't expand its $'...' construct in double quotes:
$ echo "$'a\tb'"
$'a\tb'
Change BusyBox ash to do the same. This also fixes a problem with
here documents where BusyBox ash gave an incorrect result for:
$ cat <<EOF
> '$'
> EOF
'$'
