bug#26305: 25.0.90; backward-sexp doesn't jump over the whole assignment

[lispercat]

When trying to evaluate following line:
arr = Array.new(100) { rand(1...100) }

usng ruby-send-last-sexp (C-x C-e) gives an error.
Probably the whole line or just "Array.new(100) { rand(1...100) }"
should be considered as last sexp.
