terminal.c: Reset cursor postion when using termopen() (#6212)

Browse Source 
After using 'termopen("echo") the current buffer content is changed,
but the cursor position of the current window is not updated.
Because of this, a call to 'mb_adjust_cursor()'  can lead to a
heap-buffer-overflow.

Fix this by resetting the cursor for the current window.

Fixes #3161
