I'd like to propose a followup of thread: http://lists.gnu.org/archive/html/emacs-orgmode/2011-01/msg00036.html which added a patch: http://lists.gnu.org/archive/html/emacs-orgmode/2011-01/txtZOQlKOj4dh.txt
I think this feature is interesting. Org-mode should be enabled by default as a submode inside c-mode in c-comments via Orgstruct-mode. For that the indention break "*#" proposed by the above patch should be made more general and also include the end of comment "*/" as a break if in c-mode. Org-mode inside comment would be really helpful. You could scrap all the messy doxygen and headerdoc cryptics and implement API documentation with org-mode (maybe some new features for API definition can be added to org-mode). Anyone that uses c-mode often will surely aggree (or not?). You can alredy now structure your c-comments in c-mode really nicely when using the above patch and orgstruct-mode. Give it a try. -- Konrad
