A possible bug in RECompiler.

[Guoliang Cao <ca...@ispsoft.com>]

When I run REDemo and input  "1{0,2}" or "1{1,2}" . the left screen
shows something
wrong.
I guess it's because there is a complete mechanism to handle {...},
meanwhile there is some other code add more node to represent them.  To
make it correct, we have to filter out that part.

Is this right?

Thanks for your time.

1{1,2}

0 op-branch next=24
3 op-atom next=7 "1"
7 op-branch next=14
10 op-atom next=17 "1"
14 op-branch next = 17
17 op-nothing next=20      ---- should point to the op-end directly.
20 op-atom next=24 "1"    ---- redundant, right?
24 op-end
