If you enter just a space as summary for an edit this is handled inconsistently in different places:
In the user contributions and the page history the summary doesn't show up, there are no parentheses as for non-empty summaries. This is the behavior which is correct in my eyes.
In the watchlist and the recent changes the whitespace-summary is shown: There are parentheses with a space between them, which looks a bit ugly.
At least the summary should be treated the same in every place.
