Use double quotes ("). They can be interspersed with
other whitespace characters, just like shell quoting.
A backslash (\) always escapes the next character.
The end of the stream always terminates the word.
Add AutoText struct to unit test utilities, to easily
make spv_text_t values and reference them as spv_text values.
