Documentation:
List of rules specifying number of top priority items to show.
These rules override `todo-top-priorities' on invocations of
`M-x todo-filter-top-priorities' and
`M-x todo-filter-top-priorities-multifile'. Each rule is a list
of the form (FILE NUM ALIST), where FILE is a member of
`todo-files', NUM is a number specifying the default number of
top priority items for each category in that file, and ALIST,
when non-nil, consists of conses of a category name in FILE and a
number specifying the default number of top priority items in
that category, which overrides NUM.

This variable should be set interactively by
`M-x todo-set-top-priorities-in-file' or
`M-x todo-set-top-priorities-in-category'.

You can customize this variable.
