These are fill commands, not unfill commands. Unfilling is the inverse of filling. Unfilling undoes the last filling operation on the same region or whatever. It restores contiguous whitespace chars that were collapsed, etc. What you have instead might be called "join lines" or "remove line breaks". But even those names do not accurately characterize it, because it also fills: it insists on the kind of whitespace separation imposed by filling: no contiguous whitespace chars (except possibly indentation and after sentence ends). That does not mean that this could not be useful. But we might not want to falsely advertise what it does. The best characterization of what this code does is "fill as one line". (But even that assumes a line length less than `most-positive-fixnum'.) And that is my suggestion: `fill-paragraph-as-one-line' `fill-region-as-one-line' ^ permalink raw reply [flat|nested] 8+ messages in thread

The command does more than that, e.g. it honours sentence-end-double-space. I do not think there is any need to add this command to vanilla Emacs. Just use set-fill-column (C-x f).

A user might not *need* that, provided s?he were knowledgeable wrt replacement commands or wrt Lisp. But a user might *want* that. The question is whether such commands should be added to Emacs, as a convenience. I have no opinion about that. But if they are added then I would prefer that the command names reflect better what the commands do (see my previous comment). ^ permalink raw reply [flat|nested] 8+ messages in thread

Alternatively, a bare negative prefix argument (M-- M-^) could trigger that behavior without need of an active region. ^ permalink raw reply [flat|nested] 8+ messages in thread

(I'm going through old bug reports that unfortunately weren't resolved at the time.) Looks like the command was changed to work just like this in: commit 0cd250e9583deb1e1f4d8dae2ec44c4f7c13efa6 Author: Basil L.
