ash: parser: Fix single-quoted patterns in here-documents
Upstream commit:
From: Herbert Xu <herbert@gondor.apana.org.au>

parser: Fix single-quoted patterns in here-documents
The script
x=*
cat <<- EOF
${x#'*'}
EOF
prints * instead of nothing as it should. The problem is that
when we're in sqsyntax context in a here-document, we won't add
CTLESC as we should. This patch fixes it:
