cmdrunner: Single words inside square brackets stripped from output

[djl]

What's broken?

When using cmdrunner, single words contained inside square brackets are stripped from the output.

Here's an example command:

#!/bin/sh
echo "this is a [hidden] test"
echo "this is a [hidden] test [but you can see me!]"
echo "this is a [hidden] test [hello]"

And what it looks like:

You'll notice that only the brackets containing a single word are stripped from each of the lines.
