sh: Add tests where "export" does not parse differently.

It is planned to expand variable assignments as assignments (no word
splitting, different tilde expansion) when they follow a "declaration
utility" (export, readonly or local). However, a quoted character cannot be
part of a "name" so things like \v=~ are not assignments, and the existing
behaviour applies.
