ash: parser: Save/restore here-documents in command substitution
Upstream comment: Date: Sat, 19 May 2018 02:39:42 +0800 parser: Save/restore here-documents in command substitution This patch changes the parsing of here-documents within command substitution, both old style and new style. In particular, the original here-document list is saved upon the beginning of parsing command substitution and restored when exiting. This means that here-documents outside of command substitution can no longer be filled by text within it and vice-versa.
