23.1: reverting fails to update line ending mode line |
|
Date: |
Tue, 22 Sep 2009 21:01:31 -0500 |
I had a buffer with a mode line like this:
- U:(DOS)
I ran dos2unix on the file, and did M-x revert-buffer.
The DOS stayed in the mode line until I killed the buffer and
revisited the buffer.

Since there's been no response, and my testing showed no ill effects to
this change, I went ahead and committed it in the trunk. Let's see how
it shakes out.
