One reason for not visualize spaces via faces (if `face' is not
included in `whitespace-style') is to use exclusively for
-cleanning up a buffer. See `whitespace-cleanup' and
+cleaning up a buffer. See `whitespace-cleanup' and
`whitespace-cleanup-region' for documentation.
See also `whitespace-display-mappings' for documentation."
