Bug in Git-Gui - Creates corrupt patch

Hi Shawn,

I have stumbled upon a bug in Git-GUi and am providing reproduction steps:

1.  Commit this file into a new git repository:

----------------------------- <?php

class myclass {
	public function funcAbc() {
		echo "line 1";
		echo "line 2";
		echo "line 3";
		echo "line 4";
		echo "line 5";
	}
	
	public function funcBCD() {
		echo "line 1-1";
		echo "line 2-1";
		echo "line 3-1";
		echo "line 4-1";
		echo "line 5-1";
	}
}

?> --------------

Here is the base64 encoded version:

2.  Now delete the last function in the class.  Here's the resulting
file, it is not staged or commited yet.

---------------------------- <?php

class myclass {
	public function funcAbc() {
		echo "line 1";
		echo "line 2";
		echo "line 3";
		echo "line 4";
		echo "line 5";
	}
}

?> ----------------------------

Here is the base64 encoded version:

PD9waHAKCmNsYXNzIG15Y2xhc3MgewoJcHVibGljIGZ1bmN0aW9uIGZ1bmNBYmMoKSB7CgkJZWNo byAibGluZSAxIjsKCQllY2hvICJsaW5lIDIiOwoJCWVjaG8gImxpbmUgMyI7CgkJZWNobyAibGlu ZSA0IjsKCQllY2hvICJsaW5lIDUiOwoJfQp9Cgo/Pg==

3. Using git-gui, try to stage *only* the last line marked for removal
(should be '-	}').

I get 'fatal: corrupt patch at line 22'.

4. Now try the same task using git-add -p.   Start 'git-add -p'.  Enter
edit mode (e).  Remove all the '-' lines except the last one (make
them ' ') so that only the last '-' will be removed. Save and exit.

On my system the patch is committed.

I'm running git version 1.6.0.6, 32bit linux, Gentoo OS
