Removing words in a dijit.form.Textarea will remove spaces in the underlying html textarea

[rodeoclown]

If you have text "blah foo bar" and delete "foo ", the space in front of it is replaced with a  , which is then filtered out in the Textarea.setValue() function.

This means that words can be concatenated, but this won't be visible until the value from the text area is saved, and then retrieved later.

I spent 4 and a half hours today tracking it down, and the problem is on line 90 of Textarea.js - the very first replace regEx is stripping out   and replacing it with "".

My fix was to remove the   from that regex, and add another replace call to the list replacing   with " ".
