todo-category-completions

todo-category-completions is a compiled Lisp function in `todo-mode.el'.

(todo-category-completions &optional ARCHIVE)

Return a list of completions for `todo-read-category'.
Each element of the list is a cons of a category name and the
file or list of files (as short file names) it is in. The files
are either the current (or if there is none, the default) todo
file plus the files listed in `todo-category-completions-files',
or, with non-nil ARCHIVE, the current archive file.

Before calculating the completions, update the value of
`todo-category-completions-files' in case any files named in it
have been removed.
