Bug-Reported-by:	Todd Stein <toddbstein@gmail.com>

Bug-Reference-ID:
			<Y/SHWg7/+sc19k7P@system76-pc>

Bug-Description:

There are two problems with returning tokens to yyparse() when the shell
encounters a syntax error or when it reads EOF.

When reading a WORD token, the parser has to return the correct value to
yyparse. Previous versions returned a value < 0, which the bash parser
translated into YYERRCODE for bison, and in newer versions of bison, the
appropriate reset actions didn't happen. We should return YYUNDEF, which
bison uses for `invalid token'. Since we can return a token < 0 for both
invalid tokens and EOF, the bash tokenizer needs to differentiate between
those two cases.

Patch (apply with `patch -p0'):
