Reconstruct the actual output from my unit test tool report - 95 entries
When a test fails, my unit test tool reports differences between the actual output and the expected output as follow: - line in the expected output but missing in the actual output are prefixed with a dash - unexpected lines in the actual output are prefixed with a plus sign - comments added by the unit test tool are prefixed with a question mark - common lines are showed `as-is` (well, almost;) From that "diff" format, I would like to reconstruct the actual output.

Unsemantic linewrapping - 784 entries
[Inspired by a blog post I read: https://scott.mn/2014/02/21/semantic_linewrapping/. Text adapted.] Sometimes when editing a Markdown file, I wrap the lines semantically. Instead of inserting a newline at 70 columns (or whatever), or making paragraphs one long line, I put in newlines at a point that seems logical to me. This may seem silly, but it produces better diffs. Semantic linewrapping also makes editing snappier. I can delete, edit or insert sentences easily using linewise operations. Code-oriented text editors like Vim and [REDACTED] are really good at this kind of manipulation. Editing text that hasn't been wrapped semantically is a pain, though:
