Typo in error message

[Famlam]

What steps will reproduce the problem?

1. Have a way with cycleway:right=lane and cycleway:left=lane

or

2. Have a way with maxspeed:forward=30 and maxspeed:backward=30

or

3. Have a way with sidewalk:left and sidewalk:left

What is the expected result?

Warning (in the cycleway case) Same value of cycleway:left and cycleway:left

What happens instead?

Warning (in the cycleway case) Same value of cycleway:left and cycleway

Please provide any additional information below. Attach a screenshot if possible.

Due to a few checks at or below:
https://josm.openstreetmap.de/browser/josm/trunk/resources/data/validator/combinations.mapcss#L477

- way["sidewalk:left"=*"sidewalk:right"][!sidewalk] {
- way["cycleway:left"=*"cycleway:right"][!cycleway] {
- way["maxspeed:forward"=*"maxspeed:backward"][!maxspeed] {

each with

throwWarning: tr("Same value of {0} and {1}", "{0.key}", "{1.key}");

while {1.key} refers to the non-existing tag in the [!xxxxx] selector

Solution would be easy: add [sidewalk:right] or [cycleway:right] or [maxspeed:backward] respectively as the first or second selector
