Fix a bug that could lead to duplicate links being recorded for tags.
Here I was bitten by perl's aliasing of foreach variables to the loop array contents, and match_link accidentially changed the contents of %links. In Jon's testcase, a tag added an absolute link, which was made relative by the above bug, and then the link was added again in preprocess, and turned into a duplicate.
