Sitecore link fields put /home in the target URL's href

When using sc:fld('fieldname', ., 'url') in an XSLT rendering to get a link field's target URL, you will find that the href includes '/home'. This is rarely desirable. Thankfully, it's easy to solve. Simply use sc:fld('fieldname', ., 'id') instead to get the target ID. You can then pass the ID to sc:path().
