Each item in the references section (produced by <references/>) contains a caret (used to link back to the referent) as well as letters (used if there are more than one referent). These carets and letters serve no purpose in the printable version and should be suppressed.
This requires adding a span around all these indicators, so they an be targeted by CSS.
