RFC 6570 requires repeated variables to expand to the same value.
Enforcing this at match time would require backreferences with
potentially exponential cost. We reject at parse time instead,
following the recommendation in #697.

Previously a template like {x}/{x} would parse and silently return
only the last captured value on match.
