+PREDICATE, if non-nil, is a function to filter possible matches:
+if it returns nil, the match is ignored.  If PREDICATE is nil,
+every possible match is acceptable.
+WHAT is a flag specifying the type of completion: t means `all-completions'
+operation, any other value means `try-completions' operation.
+
+This function serves as COLLECTION argument to `completing-read',
+see the Info node `(elisp) Programmed Completion' for more detailed
+description of the arguments."
