REJECT_LIMIT now can be used wonly when on_error=ignore, I think the
default(when only on_error=ignore is specified) is unlimited.
Anyway, I'm going to add a description about the default.

Considering the discussion in[1], I'm now going to remove 'infinity'.

This is because I thought it'd be more convenient to support both the
number and the ratio of error, but I'm also beginning to think that it
might be better to support only the number of cases, as discussed in
[1].
