I see, sfill.el is more wrapping than filling, maybe the name is misleading... Anyway it would be nice if sfill can be included in Emacs as it provides a nicer wrapping that is same as what you get in a WYSIWYG editor. It can be a (more capable but less efficient) alternative to the word-wrap feature. WDYT?

Btw I’ve sorted out my previous question about a faster way to get the point around column x. I seem to be incapable of solving a problem before asking it out loud in public, sorry for the noise. Now it is reasonably fast for daily use.
