show: fix formatting of multiple commands
Because we're formatting to RST, short lines wrap and there
needs to be an extra line break between paragraphs to prevent
that.
In addition, the indentation in the old code was a bit off.
Refactor the code to a function (so we don't leak variables outside
the module) and modify it so it renders more correctly.
# See http://EditorConfig.org for the specification
