Respect of the optional arg even for non-interactive use is an improvement, I think. 2. And it seems that no code distributed with Emacs calls `mark-defun' with the optional arg. So no problem there. And it is unlikely that 3rd-party code would call with the arg and expect it to be ignored (as was the case before). 3. With this at the top of *scratch* (note the blank line at top) and point between the comment and the defun, each of `M-- C-M-h' and `C-M-h' seems to loop indefinitely. -------------8<---------------- ;; This buffer is for notes you don't want to save, and for Lisp evaluation= . ;; If you want to create a file, visit that file with C-x C-f, ;; then enter the text in that file's own buffer. (defun a () nil) -------------8<---------------- 4. And with the same thing, but without the blank line at the top, both `M-- C-M-h' and `C-M-h' select the defun plus the comment, except that they do not select the first comment line. Intended? 5. `M-- C-M-h' and `C-M-h' always seem to select blank lines before the defun. Should they (what for)? 6. Interactively, I would rather see repeated use of `C-M-h', after an initial use of `C-M-h' with a negative prefix arg (e.g. `M-- C-M-h'), continue to select defuns backward. IOW, not need to use `M--' explicitly for each `C-M-h'. You can just hold down `C-M-h', to select multiple defuns forward. I would like to be able to do the same thing, but backward, by using `M-- C-M-h C-M-h C-M-h C-M-h...' (just hold down the chord). If you do that, then a negative prefix arg should not mean backward; it should just mean change direction (backward if previous command was not `mark-defun'). 7. Someone will really need to test this with more than just Emacs Lisp. The comments talk about Python and nesting, etc. HTH.
