Escape Operator

The escape character "\" has several meanings.

Inside a set declaration the escape character is a normal character unless the flag regbase::escape_in_lists is set in which case whatever follows the escape is a literal character regardless of its normal meaning.

The escape operator may introduce an operator for example: back references, or a word operator.

The escape operator may make the following character normal, for example "\*" represents a literal "*" rather than the repeat operator.
