	treated as CONSTITUENT.

	(readObject): Pass line and column to handlePostfix.

	* LispReader.java (readToken): Move ReadTable.getCurrent() out of loop.
	* LispReader.java (validPostfixLookupStart): New method.
	Requires following character to be letter, rather than any CONSTITUENT.

	useful uses of '\\' for SINGLE_ESCAPE.
	(handlePostfix): Use validPostfixLookupStart
	(readoken): Check if a character is postfixLookupOperator,
	and if validPostfixLookupStart then treat it as TERMINATING_MACRO.
