That presumably makes sense for the use of `comment-end' as "String to insert to end a new comment.", per the doc string. But `comment-end' can also be used to recognize the end of a comment, and in that case I would think that "*/", not " */", would be appropriate for C. Case in point: I have some code that does this: (while (and (< start end) (setq cbeg (comment-search-forward end 'NOERROR)= )) (setq cend (if (string=3D "" comment-end) (min (1+ (line-end-position)) (point-max)) (search-forward comment-end end 'NOERROR))) (when (and cbeg cend)...)) But that fails to DTRT with a comment such as this, because `comment-end' is not found: /* Some comment. */ So my question is whether `comment-end' should not perhaps be "*/" for C code. I do realize that `comment-skip' is available. Perhaps I should just use that somehow in my code, above? Advice welcome. I also see that there is `comment-padding', and that "the strings used as comment ends are built from `comment-end' and `comment-padding'" (doc string of `comment-region'). Perhaps `comment-end' should be "*/" and `comment-padding' as " " should be used with it to do what is done now using " */" as `comment-end' (and "" as `comment-padding')? Presumably, since lots of people have been using this for a long time, I just have something to learn wrt my code, above. Again, please let me know. Thx.
