Please don't do this!  In some CC Modes (C++ Mode, Java Mode, ...), ">"
is bound to `c-electric-lt-gt', which deals with all sorts of nasty
things that happen when ">" is a template bracket, or might be one.
(Don't blame me for the stupidity/malice of the idiots who thought that
the greater-than sign was so pretty it could be abused as a parenthesis,
leading to syntactically unparseable code.)

Please be careful when rebinding "ordinary" keys.  Particularly in CC
Mode, quite a lot of ordinary looking keys are actually "electric" keys.

Hmm.  You have an illicit '(local-set-key "\C-c\C-r" ...' in that file.
C-c C-<letter> belongs to the major mode.  You _probably_ meant to use
C-c r.  :-)
