Error detected while processing BufWriteCmd Auto Commands about vim-eunuch HOT 4 CLOSED

I've discovered the cause and a workaround, but I be interested to know your thoughts and if there is anyway to workaround it in the plugin without modifying sudoers.

That's annoying. Does it prompt for the password before spewing that error? If not, detecting the error and trying another method might not be too terrible.

No, just the error. For now, I added !sudoedit_checkdir to Defaults in sudoers but I'd rather not have to do that everywhere. Thanks

I think i'm gonna classify this as wontfix. A file in a writable directory could just as easily be removed and recreated. You may as well make the file writable too, because the security gained by making it read only is literally zero. I think sudo is trying to do you a favor, and I would need a good reason to override it.

Related: #34. If I allowed both of these, that would allow a nasty exploit where if you replace an existing file with a symlink, you can write to literally anywhere in the filesystem.
