Created attachment 1084 [details] Unify spaces in strings Some strings look like "foo bar %s...", some look like "foo bar %s ...". (Note the extra space.) This patch unifies all cases to the second one.
I tend to think that it's better without the space before the ellipsis
I think it looks better with no space before the ellipses too, but apparently that isn't the correct way to display them: http://www.kentlaw.edu/academics/lrw/grinker/LwtaEllipses.htm
I also think that's better without the space before the ellipsis, and don't believe the usage page linked by Troy has any relevance here. Ours is not the literary use of ellipsis to indicate a missing or omitted text in a quotation. On menus is a just a common GUI indicator that the menu entry has a sub-menu available and on status bar messages that the action is still being performed and we're waiting for it to finish.
Created attachment 1086 [details] Unify spaces in strings - the other way round Ok, this patch is just the other way round. Feel free to include either of them.
Gnome HIG seems to support the version with no space: http://developer.gnome.org/hig-book/3.0/menus-design.html.en#menu-item-type-command
