[Message part 1 (text/plain, inline)]

On some pair of files, "diff" reports a diff on identical lines.

I reported

  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=16848

against diff 3.3 a few years ago, but diff 3.6 (under Debian/unstable,
x86_64) has a similar problem. See the attached archive.

"out.diff", generated with "diff -u out1 out2", has at line 12622:

And if I run "diff -u -I L out1 out2", I also get the above chunk,
while it shouldn't appear.
