This means we will have to introduce the concept of different "calling
users", depending on the file being edited.

One idea would be a new file operation file-is-mine or somesuch.  For
normal files, it would return true if the file owner is
user-login-name.  For remote files, it could compare with different
users.

Most of the time, one would expect (file-is-mine "/etc/passwd") to
return false, but (file-is-mine "/ssh:address@hidden:/etc/passwd")
would return true.

Hm.

The above is very specific.  Not sure if it is better to use a
lower-level, more generic function, say file-calling-user.  For normal
files it would return the name of the user that invoked Emacs.  For
remote files it would return the name of the remote user.

What do people think?
