Subject: [PATCH] Allowed configuration token to start with a variable.

Specifically, it is now allowed to start with a variable expression with braces:
${name}.  The opening curly bracket in such a token was previously considered
the start of a new block.  Variables located anywhere else in a token worked
fine: foo${name}.
