 Log Message:
 PR bin/50993 - this is a significant rewrite of the way that here
 documents are processed.  Now, when first detected, they are
 simply read (the only change made to the text is to join lines
 ended with a \ to the subsequent line, otherwise end marker detection
 does not work correctly (for here docs with an unquoted endmarker
 only of course.)  This patch also moves the "internal subroutine"
 for looking for the end marker out of readtoken1() (which had to
 happen as readtoken1 is no longer reading the here doc when it is
 needed) - that uses code mostly taken from FreeBSD's sh (thanks!)
 and along the way results in some restrictions on what the end
 marker can be being removed.   We still do not allow all we should.
