C-x r and C-x a conflict with many default emacs keybindings

[Google Code Exporter]

What steps will reproduce the problem?
1. (require 'annot)
2. Try to use various keybindings that use C-x r or C-x a as a prefix
3. annot.el keybinding short circuits those keybindings.

C-x r is the prefix for all register, rectangular editing, and bookmarking 
commands.

C-x a is the prefix for abbreviation commands.

You can check to see if a prefix is in use by typing PREFIX C-h. E.g. C-x r C-h.

Please see this link which documents emacs keybinding conventions:
http://www.gnu.org/software/emacs/elisp/html_node/Key-Binding-Conventions.html

For minor modes the best thing to do is usually to either follow those 
conventions or don't bind any keys by default. The user has keybindings of the 
form:

C-c a
C-c b
...
C-c z

reserved for his own use (i.e. modes aren't supposed to use those).

Here is a complete list of commands blocked by annot.el.
