Subject: [PATCH] SC2163: Exporting an expansion rather than a variable.

export takes a variable name, but shellcheck has noticed that you give
it an expanded variable instead. The problematic code does not export
MYVAR but a variable called foo if any.

Add exception when using indirections where the variable to extract is
actually the value of the variable.
