[sudo-users] sudoedit in sudo-1.8.7b1 and later doesn't copy the file back post-edit

[Todd C. Miller]

Thanks for the detailed report, you are correct that it was the
direct exec change that caused the problem.  This doesn't show up
on pam systems since we need a sudo process to hang around to close
the pam session.  I've committed a fix that will appears in sudo
1.8.9rc2, to be released shortly.
