调研方向
Start by reading the visudo and sudoedit entry points and how visudo invokes an editor; the issue does not name source files or tests. Work out how permission checks and syntax validation interact before estimating an implementation. Done means visudo can support editing sudoers files as the invoking user while retaining syntax validation, including a clear response when required permissions are missing.

描述
I'd like a way to edit my sudoers file (or one of its includes) in a way that combines the best of sudoedit and visudo:
- Runs the editor as myself, like
sudoedit - Ensures I got the syntax right, like
visudo
This might be doable today using something like sudo SUDO_EDITOR=my-wrapper visudo, where my-wrapper is a script that copies the given temp file over to a user-writeable one, runs sudoedit on that as SUDO_USER, and copies the modified file back over to original the temp file.
However, I think it would be much nicer if this functionality was available built-in.
In terms of the user interface, I would think it makes most sense to just enhance visudo to detect if it is being run by a user without write access to the given file(s) (i.e. typically a non-root user). If so, rather than invoking the editor directly, it would run sudoedit; perhaps after first checking via sudo -l that the required permissions exist (in order to give a better error message if not).
If this makes sense, I'd be happy to have a go at implementing this.
