Small issue with remap of arrow keys

[jrmd54]

Normally, when the cmdline is not visible on the screen (for example I cat a large file and i have to scroll up to view the beginning of it in the terminal), pressing a key that affect the cmdline (a letter, an arrow...) moves back the visible text to the bottom of the scrollback, so that the cmdline is visible.

This does not work if the pressed key is the result of a map, for example by swapping the 'u' and 'arrow_up' keys:

map u send_key up
map up send_key u

pressing either of them will not goto cmdline if it is not visible.

Thank you very much
