Description:
At multiple points in mcom
awk is invoked in the middle of a pipeline
like this:

```shell
awk '{ print }'
```

In the context of a pipeline
it's basically a no-op,
it prints out every line as read,
performing no additional processing.

I'll send a pull request shortly,
unless this command does something more that I just don't notice.
