I installed GHC Haskell Platform for Windows. Issued cabal update. I 
then downloaded 2.4.3 darcs and in the root directory executed: cabal 
install. A few moments later, I had darcs.exe. I then installed the 
2.4.3 static linux binary on my linux host. Following is the sequence of 
commands I issued and the resulting error.

Jeremy@JEREMYCOWGAR-PC ~/josl/tmp
$ darcs --version

Jeremy@JEREMYCOWGAR-PC ~/josl/tmp
$ echo Hello > hello.txt

$ echo "Jeremy Cowgar <jeremy@cowgar.com>" > _darcs/prefs/author

We need a volunteer to reproduce this bug.
Note that the official 2.3.1 binary does not suffer from this, according
to Jeremy.

Jeremy says that when he uses the full path
(jeremy@cowgar.com:/home/jeremy/repos/darcstmp), then he gets a
complaint about not being able to mix repository formats.

With kowey's (irc nick) help, I was able to make Darcs work on Windows. We 
had to set binary mode on for a few file handles. We will work some more 
on it tomorrow and hopefully have a patch.

The following patch updated the status of issue1841 to be resolved:

* Resolve issue1841: Apply binary mode to ssh process and patch file handles.

The following patch updated the status of issue1841 to be resolved-in-stable:
