Hi Stefan,
Sorry for the late reply.

This is by design. This is as in Racket, where there is a difference
between syntax-local-value and syntax-parameter-value. In master, there
is an additional parameter to resolve-identifier,
`resolve-syntax-parameters?'.
Suggestion: if you want this, add a similar parameter to psyntax.scm in
stable-2.0, and in both branches plumb it through to a keyword argument
on syntax-local-binding. Update the docs, too :) You had the
beginnings of a patch on bug 10992.
Thanks!
Andy
