Subject: 2005-06-08  Frank Ch. Eigler  <fche@redhat.com>

	systemtap/916
	Implement all basic scalar operators, including modify-assignment.
	* parse.cxx (lexer): Allow multi-character lookahead in order to
	scan 1/2/3-character operators.
	(parse_boolean_or/and/xor/shift): New routines.
	* translate.cxx (visit_assignment, visit_binary_expression,
	visit_*_crement): Generally rewrote.
	(visit_*): Added more parentheses in output.
	(emit_module_init): Initialize globals.
	* staptree.h, elaborate.cxx, elaborate.h: Remove exponentiation.
	* main.cxx (main): Add an end-of-line to output file.
	* testsuite/*: Several new tests.
