AFAIK this is not an error, just a message (that you can safely ignore).
The mode is enabled nonetheless and should work as expected.
Background: There is a feature that hi-lock-mode searches for pattern
specifications of the kind
Hi-lock: FOO
that define initial highlightings.
Since the help buffer of `hi-lock-mode' explains this feature, it
contains a match for the regexp searched for (namely "Hi-lock: FOO") but
hi-lock-mode discards it because it is invalid (thus the message). So
this issue is only a coincidence appearing only in the help buffer of
`hi-lock-mode'. FWIW I can live with this message in this special case,
though I agree that it is confusing.
Michael.
