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 - 663 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:

Song Transcription Oops - 197 entries

When transcribing vocal music to Canjo Tab you can start by finding the lowest note and assigning that to zero and working your way up from there. However, without fail, I tend to miscount the notes and when I am near done I find a lower note. I mark this with a "z". This means I have to increase all the previous ones by 1. just a sting of numbers :)
