SSI: avoid potential buffer overflow.
When "-" follows a parameter of maximum length, a single byte buffer
overflow happens, since the error branch does not check parameter length.
Fix is to avoid saving "-" to the parameter key, and instead use an error
message with "-" explicitly written. The message is mostly identical to
one used in similar cases in the preequal state.
