Subject: bug#19032: 24.4; icomplete cannot select matches with C-x b with no input
Date: Thu, 13 Aug 2020 12:00:07 +0200 [thread overview]
Message-ID: <CANb2OvL7TWf+G9kmdfmd8E5CPVVrTn+X31+V6mHx4i5Uo-mb2g@mail.gmail.com> (raw)

Thanks!
I'm a former iswitchb user, and this problem keeps me from switching
to icomplete (I'm currently on ido-switch-buffer), even though I would
like to have access to more advanced completion.
