vi: basic undo feature shouldn't depend on yankmark

Currently basic undo functionality with the 'u' key depends on
FEATURE_VI_YANKMARK. These two features are separate, so we can remove this
dependency.

vi: fix reading of file after last line
...
If the :r command is used to read a file after the last line of the
buffer the last line of the buffer and the first line of the file
are joined. An extra blank line appears at the end of the buffer.
file 1
file 1
file 1file 2
file 2
file 2
~
~
The insertion point is normally at the start of the line following the
specified line. When the specified line is the last one the next_line
function baulks at moving to the non-existent following line.

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).

fixed the 'c', 'd', and 'y' commands to properly handle both motions

instance, now "c%" and "2cw" work correctly, whether the motions span
lines or not.
