Additional changes from Chris Siewald relating the the "J=" bug
reported to the jamming mailing list by Paul Forgey on Oct 12.
These changes address issues with constructs such as:
A = a b c ;
B = ;
C = A B ;
echo $($(C)[1-2]:J=.) ;
echo $(A[1-2]:J=.) ;
Which now prints:
a.b
a.b
Which seems like the correct behavior to me.. (?)
However, this change seems to alter the behavior of this construct:
FOO = foo ;
VAR = a b ;
BAR = FOO VAR ;
Echo $($(BAR):J=.) should be $(FOO:J=.).$(VAR:J=.) ;
