parser: Fix backquote support in here-document EOF mark
Upstream commit: Author: Herbert Xu <herbert@gondor.apana.org.au> Date: Thu Mar 15 18:27:30 2018 +0800 parser: Fix backquote support in here-document EOF mark Currently using backquotes in a here-document EOF mark is broken because dash tries to do command substitution on it. This patch fixes it by checking whether we're looking for an EOF mark during tokenisation. Reported-by: Harald van Dijk <harald@gigawatt.nl> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> With added fix for quoted-ness of the EOF mark. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
