C-M-o, on something like: foo bar baz ^ point will split the line into foo bar baz , but will leave a trailing space on the first line. This is in accordance with its documentation in emacs.info, but this peculiarity isn't mentioned in the doc string. I find this trailing space irritating, as I frequently have to remove it by hand. What is the motivation for this trailing space, and do we really want it? -- Alan Mackenzie (Nuremberg, Germany).
