So at the very least it sounds like I can add + to the list of characters?

But I'm still curious about why the regex has a list in the first place.
Does anyone know why it was done this way, or if there are nonspace
characters that we should be careful not to pull in?  Is it just so that a
URL in prose does the expected thing, such as:

"You might look at http://example.com/foo, but it's not a very good site."

You wouldn't want the comma in that case.  Or if it were quoted with
single or double quotes, etc.
