1. My opinion is that \n line endings on Cygwin (a Unix-ish environment) are less surprising.  
2. Cygwin already has a feature for determining line endings for files opened in text mode, and a corresponding install setting for the default (dos versus unix).  If you wanted a default CR-LF ending out of Emacs, you could get it that way.

That is interesting. However my problem is with line endings. It turned 
out that the file to patch has CR-LF line endings (which is ok) and the 
patch file had LF line endings. This surprised me, I did not notice it 
first. In my opinion it should not have had that. It came from 
Thunderbird on MS Windows and I just pasted into a new file in Emacs. 
Then Emacs made the decision to save the file with LF line endings.

There are two things I would like here:

*** For patch: I would like it to discover that the line ending type of 
the patch file and the file to patch differ. I would then like patch to 
convert the line endings in the patch read from the patch file to that 
kind used in the file to patch. (It should not change the patch file of 
course.) That would be enough to solve my problem. However I would like 
such functionality to go into the main patch distribution if possible. 
That would save work I hope.

*** For Emacs: I would like the default on MS Windows to be CR-LF line 
endings. That would in my opinion be less surpricing for an MS Windows user.

Patch does that already if you use the --binary option on Windows.

We decided long ago to preserve the EOL format, and I think that
decision was correct.  As I wrote elsewhere, I use Patch from within
Emacs on Windows with no problems at all.  Emacs has commands to force
specific EOL types when it saves files and communicates with
subordinate programs, so the defaults are not really important.
