For the record, this would have worked w/o the double quotes (which I
thought would have not), but it is somewhat safer for someone to copy
this to some use. If there were literal '>'s in the line, then those
redirections would have been done in 'eval' (with these quotes). Without
quotes, '>' redirection would have been done before 'eval'. But 
when '>' is given in variable $2, the redirection would have been
done in eval (after shell has expanded the line for it) in any case.

all that said, this particular change OK...
