This is meant more as a question rather then actual code fix intention:
I have a problem with sudoedit cmd line tool only accepting password from ksshaskpass if it is provided with newline in the end. Specifically in current state - calling:
EDITOR=kate SUDO_ASKPASS=/usr/bin/ksshaskpass sudoedit -A /etc/hosts
...will result in a Ksshaskpass dialog and after entering the password the command just ends. But after applying this patch it starts working and kate is opened.
I tried other graphical askpass programs, namely ssh-askpass, qt4-ssh-askpass, lxqt-ssh-askpass and gnome-ssh-askpass2 (gtk2). They all work nicely with sudoedit.
My question is: Is it intentional that the password is not returned with newline? Should I ask sudoedit guys instead? Or is the problem elswhere, e.g. in KPasswordDialog (KF5 kwidgetaddons)? Thanks!
PS: Please add reviewers as needed, I don't know the proper flow here, sorry :).
