Add spaces between watchlistedit-raw-done, watchlistedit-raw-added, and watchlistedit-raw-removed messages.

When submitting the raw watchlist edit form, the results page displays the watchlistedit-raw-done, watchlistedit-raw-added, and watchlistedit-raw-removed messages with no spaces in between. This results in display along the lines of "Your watchlist has been updated.1 title was added:", missing a space between the two sentences.

The attached patch will fix the issue. If items were both added and removed, the HTML will contain one unnecessary space before the watchlistedit-raw-removed message, but this does not affect the display of the page in the browser.
