Jilles Tjoelker 5d91007000 sh: Fix a crash if a heredoc was not properly ended and parsing continued.
Example (in interactive mode):
  cat <<EOF && )
The next command typed caused sh to segfault, because the state for the here
document was not reset.

Like parser_temp, this uses the fact that the parser is not re-entered.
