normalize scenarios (#1711)

Closes #845

**All changes are non-significant whitespace.**  This can be verified with:

    git show --ignore-all-space --ignore-blank-lines

in which the remaining changes are only elimination of manual word-wrap in descriptions.

Normalization is accomplished with this command:

    scripts/normalize-all-scenarios.sh

This is an initial normalization pass that shall be a pre-requisite for #1713.
