[PATCH] teach show_special() to handle tokens introduced by evaluate_comparison()
Fix handling of replaced comparisons in expression. We are handling
unsigned comparisons by replacing the expr->op with new special values
(SPECIAL_UNSIGNED_{LT,GT,LTE,GTE}) which works fine, but confuses the
hell out of show_special(). As the result, test-linearize simply
segfaults on any code that contains unsigned comparison.
This patch fixes that by teaching show_special() to handle these guys
and making sure that tokenizer doesn't get confused (it uses the same
set of strings to recognize punctuators).
