Actually, I don't think it's either. I think we're going to have to wait
until issue 8 for these.

I see the problem. The parser handles assignment statements preceding a
command word, and marks assignments following declaration commands as
assignment statements requiring special handling. The word expansion code,
possibly making assumptions about when in the expansion process it will be
called, does not. I will change this for 4.3-beta so the two are consistent.
