undo info for *cvs-tmp*

[Dan Nicolaescu]

Every time when commiting something to emacs CVS this warning appears:


Warning (undo): Buffer ` *cvs-tmp*' undo info was 3642818 bytes long.
The undo info was discarded because it exceeded `undo-outer-limit'.

This is normal if you executed a command that made a huge change
to the buffer.  In that case, to prevent similar problems in the
future, set `undo-outer-limit' to a value that is large enough to
cover the maximum size of normal changes you expect a single
command to make, but not so large that it might exceed the
maximum memory allotted to Emacs.

If you did not execute any such command, the situation is
probably due to a bug and you should report it.

You can disable the popping up of this buffer by adding the entry
(undo discard-info) to the user option `warning-suppress-types'.




Not sure what is the right solution here, completely disable undo for
*cvs-tmp* or up the limit. Can somebody please take a look at this? 

Thanks!
