translation of turn restriction icons not perhaps a good idea

[nfgusedautoparts]

JOSM, in displaying turn restrictions, currently uses a set of translation tables derived from the turn restrictions proposal page. there are cases where these translations (e.g., no left turn becomes right&straight permitted) are inappropriate, as they do not take into account underlying facts like oneway conditions on the ways (for example, no left turn may be the sign at the corner, and is correct, but the road to the right may be oneway into the intersection, so straight&right only is not an appropriate translation.)
JOSM should either refrain from making the translation in its display, or should check the underlying ways before making the translation. in its current form, it is misleading and can lead to users doing the wrong thing with the turn restriction relation in order to get a display the agree with.
