Switching topics, this commit (9e2d870119) adds the following help message:

On the other hand, SAVE_ERROR_TO takes 'error' or 'none', which
indicate "immediately error out" and 'just ignore the failure'
respectively, but these options hardly seem to denote a 'location',
and appear more like an 'action'. I somewhat suspect that this
parameter name intially conceived with the assupmtion that it would
take file names or similar parameters. I'm not sure if others will
agree, but I think the parameter name might not be the best
choice. For instance, considering the addition of the third value
'log', something like on_error_action (error, ignore, log) would be
more intuitively understandable. What do you think?

regards.
