SUMMARY
Scrolling with the mouse wheel in man or less doesn't work.

STEPS TO REPRODUCE
man
1. Open a man-page.
2. Move the scroll wheel of your mouse.
3. man exits.
4. The characters "OB" are printed on the terminal.
If you scroll using the arrow keys first, the mouse wheel might work a little as expected, but will eventually cause 3 and 4.

less
1. Open a file with less.
2. Move the mouse wheel to scroll down.
3. The bell symbol shows up but no scrolling of the content happens.
4. Hit space or one of the arrow keys.
5. Now the mouse wheel works as expected.

EXPECTED RESULT
Moving the mouse wheel makes the content scroll all the time.

ADDITIONAL INFORMATION
Im pretty sure that this used to work in an earlier version. However, I don't know which one.
I also tried scrolling with the mouse in vi: This causes no problems.
