Failure to step up in corners when wishdir is towards a wall
When the player's mouse angle is towards a wall at less than 90 degrees, they can move along the wall with +forward, but usually cannot step up while jumping. This can be reproduced easily on maps like cpm_1 (the obstacles are too tall to get over with the height of a jump).
This is a different bug from #2821.
