Description of problem

Dokku output is polluted with a lot of noise related to (I think) the bash environment. This occurs both when using dokku commands on the host, and in the output when running git push dokku.

The host is running Debian Buster. Dokku itself is 0.20.4, installed via the wget/bootstrap.sh method.

All operations do seem to complete successfully. Sample output below.

The output is less significant in some commands, for example, when using dokku config:* commands, nothing is seen. In others, like a git push, more than 70% of the output seems to be these lines.

How reproducible

• Run any dokku command on the host.
• Push to the dokku remote.

Actual Results

This is a sample, but representative.
