ash: parser: Fix single-quoted patterns in here-documents
Upstream commit: From: Herbert Xu <herbert@gondor.apana.org.au> Date: Fri, 9 Mar 2018 23:07:53 +0800 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: Reported-by: Harald van Dijk <harald@gigawatt.nl> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
