* c-typeprint.c (c_print_type): Don't crash if varstring is null.
* expprint.c expression.h (dump_expression): Rename to
dump_prefix_expression.
* Print out the expression in normal form. Call print_longest
instead of trying to do it ourselves.
* (dump_postfix_expression): New function, prints out the expression
with indentation and better formatting and interpretation.
* parse.c (parse_exp_1): Put calls to dump expressions under ifdef
MAINTENANCE_CMDS and expressiondebug variable.
