address@hidden: Buffer sometimes changes to modified with truncate-partial-width-windows set to nil]

[Richard Stallman]

This bug is important to fix.  It probably has to do with the recent
font-lock changes.  Would someone please start working on it?

X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=failed

1. start emacs -Q
2. in scratch buffer evaluate the following 2 expressions
(setq ediff-split-window-function 'split-window-horizontally)
(setq truncate-partial-width-windows nil)
3. M-x ediff-files file1 file2

Now when I move (with <n> in Ediff Control Panel) from diff to diff, it's
only a matter of time till at least one of the buffers changes the
buffer-modified flag without any apparent reason.
