ash: parser: Fix old-style command substitution here-document crash
Upstream commit: Date: Fri, 29 Mar 2019 13:49:59 +0800 parser: Fix old-style command substitution here-document crash ... This is caused by the recent change to save/restore here-docment list around command substitutions. In doing so we must finish existing here-documents prior to restoring the old here-document list. This is done for new-style command substitutions but not for old-style. This patch fixes it by doing it for both. Fixes: 51e2d88d6e51 ("parser: Save/restore here-documents in...")
