I noticed a problem when working with git-gui which might be a bug. The issue only affects you when you are visually trying to stage changes line by line. Here are the steps to reproduce the problem: 1. Initialize a new repository. 2. Create a file with three lines of content each with the word "Hello". Do not put a new line at the end of the file. 3. Add and commit the file. 4. Edit the same file putting words inbetween the three lines. 5. Open git-gui and try to stage the changes line by line. The editor will append the warning "No newline at end of file” to the end of the diff. When you are trying to stage a line an error occurs. The problem is also illustrated in a question on Stackoverflow [1]. Please let me know if you need more information or if I should send this problem to some other mailing list.

The "\ No newline at end of file" is emitted by git at we don't appear to handle it well in the lib/diff.tcl apply_range_or_line function. >> ---------- Forwarded message ---------- >> From: Tobias Preuss >> Date: Tue, Nov 13, 2012 at 9:26 PM >> Subject: git-gui / Warning: "No newline at end of file” >> To: git >> >> >> Hello. >> I noticed a problem when working with git-gui which might be a bug. >> The issue only affects you when you are visually trying to stage >> changes line by line.
