If I run a cygwin command (for example ls, or for a simpler example, "printf hello\nthere", although the latter needs care to get the correct level of \n escaping :-)) newlines are displayed by the text moving down a line, but *not* returning to the left hand margin. An example, running in Powershell as my shell: >E:\Utils\Cygwin64\bin\printf.exe hello\nthere hello there This behaviour is present with the latest version of cygwin1.dll, as well as with the 20200212 snapshot. It is not present if I replace the Cygwin dll with version 3.0.7-1. The problem does not appear with a standard cmd.exe terminal (standard Windows console host) or the new Windows Terminal application. I understand that ConEmu handles the console management differently "behind the scenes" to present a GUI front end, but I don't know enough about the internals to know how it does that. I can work around the issue by pinning to cygwin 3.0.7-1, but it's obviously not ideal. I have been unable to find any details as to what changed between cygwin 3.0.7-1 and the next version to help me track down the issue any more specifically. There are some notes at https://conemu.github.io/en/CygwinMsys.html that I've read, but to be honest I don't entirely understand. I did, however, confirm that this issue doesn't occur in a standard `cmd` window (and I added that information to the ConEmu issue report). Any information that would help to pin down the cause of this problem would be very much appreciated.
