How can you tell how many people would like to use it, or indeed if anyone uses it at all?
At any rate, thanks for this fix. It is extremely helpful, and even provides a workaround -- to a degree! -- for the line-wrapping problem, as long as one is writing a document in a markup language like TeX/LaTeX or XML where line breaks are treated the same as spaces. However, the line-wrapping bug is still a major annoyance, at best, and until it is fixed, Emacs cannot claim to be Unicode compliant. I saw that Mr. Stallman chimed in on the line-wrapping bug, does this mean that there's hope that it will get fixed in the forseeable future?
