This is expected behaviour.
``The
Index line, if present, takes precedence over the context
diff header.''
Options like -p1 are applied after guessing the filename, so it will
be applied to `b/file' in your case, stripping the `b/' of it, and
leaving just `file'.
``Fixing'' this behaviour would royally screw CVS diffs that heavily
rely on the Index: magic.
