Pasting long lines to wrapped view inserts unwanted newline characters on linux

First of all, thanks the great project. It makes UI creation easy and intuitive.

I have the following issue: if I paste a longer line than the view's width, it breaks the line as the image shows:

It works as expected, when I type a long line instead of pasting.

simplified demo code to reproduce (paste 50*'a' to the view):

go
package main

import (
	"log"

	"github.com/jroimartin/gocui"
)

func main() {
	g, err := gocui.NewGui(gocui.OutputNormal)
	if err != nil {
		log.Panicln(err)
	}
	defer g.Close()

	g.Cursor = true
	g.SetManagerFunc(layout)

	g.SetKeybinding("", gocui.KeyCtrlC, gocui.ModNone, quit)

	if err := g.MainLoop(); err != nil && err != gocui.ErrQuit {
		log.Panicln(err)
	}
}

func layout(g *gocui.Gui) error {
	maxX, maxY := g.Size()
	if v, err := g.SetView("hello", maxX/2-17, maxY/2-1, maxX/2+17, maxY/2+4); err != nil {
		if err != gocui.ErrUnknownView {
			return err
		}
		v.Editable = true
		v.Wrap = true
		g.SetCurrentView("hello")
	}
	return nil
}

func quit(g *gocui.Gui, v *gocui.View) error {
	return gocui.ErrQuit
}

Do you have any clue how could this be fixed/avoided?
