handle all binary operators the same when detecting command syntax (bug #60882) This change breaks Matlab compatibility when parsing things like x += 2 Matlab will handle this as a command-style function call with two arguments '+=' and '2'. Octave will now treat this as a computed assignment (the variable X incremented by 2). Octave will still handle x +=2 as a command-style function call when parsing this statement inside a function. At the command line, Octave will recognize this statement as a computed assignment expression if X is already defined to be a variable. Note that command lines are parsed completely before executing anything, so in octave> clear x octave> x = 1; x +=2 the "x +=2" statement will be parsed as a command-style function call because the parser does not find a definition for X as a variable when that portion of the command line is parsed. * lex.ll (CMD_OR_COMPUTED_ASSIGN_OP): Delete macro. Change all uses to CMD_OR_OP instead. (base_lexer::handle_identifier): Don't call mark_may_be_command for token if we are at the top level and the identifier has already been recognized as a variable. * parser.tst: Update test.
