I have the same question.
I think the circumflex ^ makes it start at the start of the string, and $ makes it start at the end, but otherwise I'm not sure.
Also, "/^\" wouldn't do anything, it's only "/^\ " that would do something, because the \ character "escapes" the space. "\ +" matches all spaces in the document.
Google doesn't really give much in the way of answers, either.

' ~ s/\s+$// ' - it doesn't really remove the trailing whitespace. any alternative to do the job?
