The additional optional argument for `goto-line' is a good idea. Commit that any time, as far as I'm concerned.

I object to the removal of the comment about "unwanted side effect" in the documentation string of `next-line-add-newlines'. When it's non-nil `(while t (next-line 1))' can crash your XEmacs, and possibly your system, with an out-of-memory error. It will corrupt your file if used in a macro with a large repeat count. Etc. Do change "FSF" to "GNU" if the statement about their default is correct, and I don't care that much about the Steve Baur comment, it was old when I joined the project :-).
