In a first approximation, the details are actually quite simple:

- Any `#debug` statement that does not end in a `\n` will be 
concatenated with the next one.

- Any `#debug` output after the last `\n` may be truncated.

No, the "use forward slashes instead" rule only applies to filenames; 
the change was made /specifically/ so that `\n` is always interpreted as 
a line feed (as opposed to a path separator followed by the lowercase 
letter `n`).
