[PATCH] Scanner fixes and tweaks

Hi all, First, I just realized while going through the scanner code after the re2c changes that there's a bug with heredoc handling (from my code changes last year, oops) on something like: <<<EOT text fooEOT text EOT; Patch for 5.2 with just that fix: http://realplain.com/php/heredoc_fix_5_2.diff For 5.3 and HEAD, I fixed problems with yyleng (some would only affect highlighting, tokenizer ext, etc.) Double quoted heredocs with tabs/spaces wouldn't work right (ex: <<< "EOT"). Updated some comments. And this rule that was added... <ST_LOOKING_FOR_PROPERTY>{WHITESPACE}+ { /* do nothing */ goto restart; } Would lose that whitespace in highlighter, etc. or miss counting line numbers. Speaking of line numbers, I also removed the CG(comment_start_line) variable since I can't see that it's needed anywhere, and CG(zend_lineno) works for the "Unterminated comment..." warning (which isn't working right now anyway :-)). In HEAD I also tidied up the LNUM/HNUM rules which lost their tabs and Z_* macros a year ago (v1.164). http://realplain.com/php/scanner_fixes.diff http://realplain.com/php/scanner_fixes_5_3.diff - Matt
