Use line length to wrap usage (#2457)

Specify the `usageLineLength` in our command and command runner. Use the
terminal width or default to 80 if it is unknown.

Remove manually placed newlines in a help string with a space so that
it can wrap based on terminal width. For a width of 80 the wrapping
matches the manual newlines.
