Change approach to handling errors

The approach from 7b210fc (Ignore standard error stream when digesting
output, 2016-09-01) does not work well because, depending on the
snakemake subcommand, the text of interest may be in the stderr stream.
Instead, use lines with spaces as a way to detect non-target lines.
