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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
