Whilst applying the correction I found that pasting the prow_ref tag to the revised sections of the path was applied incorrectly by JOSM. Should be OK now.

That tag is not correct so I will remove it; not sure how that mistakenly crept in. Thanks for pointing it out.

Thanks Bernard. Whilst away I was using a touchscreen tablet to make some minor corrections following a walk and must have inadvertantly dragged the outline.
