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.
