[PATCH] Touch up a few docstrings.

[Kyle Meyer <kyle@kyleam.com>]

* gwl/processes.scm (processes-filter):
* gwl/workflows.scm (auto-connect): Fix typo.
(print-workflow): Rephrase repetitive wording to be consistent with
style of surrounding docstrings.
(workflow-run-order): Convert parameter to upper case.
