Hmmm, I would have thought that foreach would still
only iterate over the original elements of $options (since foreach
takes the values of $options, not the variable reference),
no matter if you lappend to options; or am I confused, and
does it really keep iterating over newly append items?
It would seem like those "lappend options" are actually dead
code. Otherwise, appending to `options' means that those
new items always ended on $new_options after
all the original options, but I don't think it matters
here. Either patch looks ok to me, although you got me a
bit confused with tcl's foreach now. :-)
