             Summary: svn patch adds newline to last line of file with svn:eol-style
                 Key: SVN-4906
                 URL: https://issues.apache.org/jira/browse/SVN-4906
             Project: Subversion
          Issue Type: Bug
          Components: cmdline client
    Affects Versions: 1.14.2
            Reporter: Nathan Hartman
         Attachments: reproduction-script.txt

When a versioned file has the svn:eol-style property, the last line of the file does not end with a newline, and the user applies a patch with 'svn patch' (where the patch does not contain changes to the last line or any lines near it), 'svn patch' adds a newline to the last line of the file.

I've confirmed that the same issue is reproduced for all possible values of svn:eol-style (native, LF, CRLF, CR).

This issue was found by Vincent Lefevre, who provided the following reproduction script (see attachment).
