lineedit: small fixes

Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

line editing: add an option to emit ESC [ 6 n and use results

This makes line editing able to recognize case when
cursor was not at the beginning of the line. It may also
be adapted later to find out display size (serial line users
would love it).
