I've also found a long-running problem, where emacs won't load certain files that are configured to load and be edited in emacs. This shows what I have configured for emacs-25 during its build process - --8<---------------cut here---------------start------------->8--- Configured for 'x86_64-pc-linux-gnu'. Where should the build process find the source code? . What compiler should emacs be built with? gcc -g3 -O2 Should Emacs use the GNU version of malloc? yes Should Emacs use a relocating allocator for buffers? no Should Emacs use mmap(2) for buffer allocation? no What window system should Emacs use? x11 What toolkit should Emacs use?

Basically it seems that certain files, like [[~/.emacs.d/org/keybindings.txt]] works, but [[~/cron/boudiccas.crontab]] doesn't. Drew suggested when I last raised this issue that it was because of my config. Okay, but I only go with the default config, like './configure', so what else should I use instead then please, to get all files that have been worked on, written, etc to open in emacs form an org-mode link, as I've just shown please?
