Thanks for the reply Peter.

No, I "unsetopt globassign" to make sure, even though it did not show
in the list of currently set options, but it still works from the
command line.  I was trying to do it this way because the script I am
working on is running in sh emulation mode and doing it as
"files=/bin/c*" assigns it as a single string.  I ended up going ahead
and changing the one function to zsh mode and doing it as a list to
get around the problem, but I wonder if I have stumbled onto a bug
here.
