Requiring an additional argument `op' means that we wouldn't
be able to customize `hi-lock-read-regexp-defaults-function'
to just `find-tag-default' or `find-tag-default-as-regexp'.
I think there is no need to distinguish between different
hi-lock commands since one user would very likely prefer
the one way to get the default for all hi-lock commands,
so you could call `hi-lock-read-regexp-defaults-function'
without arguments.
