[Xotcl] RE: Non-positional args with no value cause core dump

I found another problem with non-position args... an argument of "--" can cause a core dump.
Consider the following.


Object o
o proc foo {{-a A}} {b} {
   puts "$a $b"
}
o foo "B"
#--> "A B"

o foo "-"
#--> "A -"

o foo "---"
#--> "A ---"

o foo "--"
#--> core dump.
