Fix the following issues in the test suite:
- lack of quoting for variables
- declare function variables local when missing (prevent accidental

- for variables with underscore in the name use plain "$VAR_NAME"
instead of { } (unless necessary)
- minor style adjustments like moving quotes to the end of the same
string
