Word wrap takes last word from the previous line with it when followed by spaces that reach the width of window and trigger word wrap.

Issue
When text (words) reach just before the end of the line, at the window width and point of word wrap, if you follow the last word with enough spaces (whitespace) the last word of that line is taken to the following line. If you continue with enough spaces, xed becomes more and more unresponsive.

Steps to reproduce

• Enable word wrap.
• Type a handful of words.
• Make the editor window width wide enough not to trigger word wrap on the last word.
• Now start typing spaces.
• Notice that when word wrap is triggered, the last word of the line is taken to the following line.
• If you continue with enough spaces, then the editor becomes more and more unresponsive. :-(

Expected behaviour
Line-wrap should wrap on words not spaces?
Also, adding spaces to a line should not cause xed to become unresponsive.
