[New-bugs-announce] [issue27709] difflib.HtmlDiff produces different output from difflib.ndiff

[SilentGhost]

New submission from SilentGhost:

msg264842 in issue26945 reports an odd results of HtmlDiff.make_file, digging into it I've noticed couple of things: different output to one generated directly from difflib.ndiff and underlying issue further up the stack that generates same faulty output with a slightly modified files.

The patch I'm attaching fixes the issue with different outputs, from make_file and ndiff, by not removing EOL characters, I had to re-generate expected test output file.
