kwic crashes with vector window

[kbenoit]

This crashes R:

library("quanteda")
kwic("This is a sample text.", "sample", window = c(1, 2))

It is because the C++ function expects single value. I did not checking the value because a vector just cause errors on Linux and Windows. Isn't it the same on Mac?

> kwic(toks, "people", window = c(1,2))
 Error in qatd_cpp_kwic(x, attrs[["types"]], ids, seq_along(ids), window,  : 
  Expecting a single value: [extent=2].
