mult_isarr bug

mult_isarr bug

[Peter Stephenson]

Am I going crazy or is this bug still in the latest version of the shell?

% dirs
~z/Src ~z ~/lgt/rz2 ~ ~/lgt/tfuzz /temp/pws ~/lgt/su2/cxx ~/tex/hep-lat
/temp/pws/src
% print ${$(dirs)[1]}
~

Wasn't this just fixed?

Oops. No, we have only handled nested parameter expansions, yet.

The `fix' for the above would be something like the patch below which
makes the result of $(...) be treated as an array if the whole thing
is not quoted. I think this is the right behavior, yes?
