> {{grep -o}} appears to be writing truncated files. missing a flush, maybe? i do not observe the same behavior with {{scan -o}}

> There are a couple extra rows in the redirect output explained by the log messages, but not 100. The final line in grep_-o.out is truncated in the middle of the row column.
> If I include some terms in the grep to limit the output, I often get zero-length files via -o despite seeing results when run interactively.
