Log Message:
After discussions with Jilles Tjoelker (FreeBSD shell) and following
a suggestion from him, the way the fix to PR bin/50993 was implemented
has changed a little.   There are three steps involved in processing
a here document, reading it, parsing it, and then evaluating it
before applying it to the correct file descriptor for the command
to use.  The third of those is not related to this problem, and
has not changed.  The bug was caused by combining the first two
steps into one (and not doing it correctly - which would be hard
that way.)  The fix is to split the first two stages into separate
events.   The original fix moved the 2nd stage (parsing) to just
immediately before the 3rd stage (evaluation.)  Jilles pointed out
some unwanted side effects from doing it that way, and suggested
moving the 2nd stage to immediately after the first.  This commit
makes that change.  The effect is to revert the changes to expand.c
and parser.h (which are no longer needed) and simplify slightly
the change to parser.c. (from kre@)
