and lexer files). From now on, the following Emacs cc-mode settings apply when indenting C function bodies in InnoDB: (setq c-basic-offset 8) (setq c-label-minimum-indentation 0) (add-to-list 'c-offsets-alist '(c . 0)) (add-to-list 'c-offsets-alist '(label . [0])) The indentation rules for function declarations still have not been formalized, and they must be formatted manually. Try to limit all lines to at most 79 characters (assuming TAB stops every 8 characters) by splitting lines before opening parenthesis, or at string constants. Fix some grammar mistakes in diagnostic output: match to, match with -> match found from -> found in trying rename -> trying to rename Fix an error in page_check_dir(): it said "supremum not pointed to" when the infimum was not pointed to. Enclose commented-out code snippets in #if 0 ... #endif instead of /* ... */. Add (void*) casts to some %p parameters in fprintf() calls. Try to split lines before a binary operator, not after one. (These three fixes were not made everywhere.)
