Output: final newline / "old line"

With the following output there are some problems:

1. what does old line mean? Should be removed or replaced with some more descriptive message (in verbose mode only?)
2. it is missing a final newline - as you can see since Zsh prints timing information in the same line
3. it displays “1484 out of 133”, i.e. the count / total appears to be off. It would be good to see what it refers to (mutations? files?)

1. Probably. It seems a bit messy due to the way I handle the dict synonyms option though, I might just only support that via the config file or maybe store it in the cache? Hmm… I’ll have to think about it a bit, but in general it seems a lot nicer, I just didn’t find it in the docs when I was implementing this.
2. I guess. You can just pull up another terminal and print the results during execution.
3. I see you figure it out 😛
4. Name? What do you mean? I don’t really have names and I don’t see how that would help much if I did…
5. Embarrasing! I’ll fix that in 1.0.1 😛

I’ll fix the missing newline at the end in 1.0.1 too.

Fixed again 😛 Thanks for the bug report.
