I believe the "+" indicates that there are some Windows permissions that 
do not map to the Unix-style user/group/other.  For example, if I create 
a new file using cygwin (say, with touch), and then open the file's 
properties with Windows and explicitly add permission for another user 
to modify the file, I see the "+".

Well, you can copy all the file attributes from one file (sourceFile) to 
another (destFile) with a command like this:

% getfacl - sourceFile | setfacl -f- destFile

Do "M-x customize-apropros" on "backup-by-copying".  The default 
behavior is to move the old file to the backup file and then create a 
new file.  If you set this option on (non-nil), the backup copy will be 
made as a copy and the original file will be modified.  This will 
preserve the extra file permissions on the original file (although the 
backup copy won't have them).

HTH,
Dave
