Passing large input to PagedSeq.fromString causes StackOverflowError

[filipochnik]

test case:

        val len = 10000
        val i = Iterator.fill(len)("A")
        val pagedSeq = PagedSeq.fromStrings(i)
        pagedSeq.slice(1)

error:

[error] Test scala.util.parsing.input.gh64.test failed: java.lang.StackOverflowError: null, took 0.006 sec
