If a file did not end with a newline, html-report would not output it.

I couldn't find any tests for html report. Maybe it's worth having some.

The canonical way to solve this kind of thing is probably s.rstrip('\n') [EDIT: strip -> rstrip]

mypy/report.py Outdated
number=str(lineno),
precision=stats.precision_names[status],
content=line_text)
content=line_text.strip('\n'))

Sorry, rstrip().

Well, it should still be the same, since we know we are always processing one line. But rstrip() is probably better stylistically.

Originally, I was worried about removing legitimate newlines in the code. But they will be escaped and therefore won't be removed.
