vi: reject change command when motion fails
If the motion command used to define the range of a change, yank or
delete fails the whole command should be rejected. BusyBox vi already
handled failed searches in these circumstances. Add some more cases:
- non-existent mark: d'x
- movement beyond end of file: c99999+ or 99999<<
This is implemented using a global variable which is set when a command
error is detected. Unlike the case of motion within a line it's
insufficient to check that the motion command doesn't move the cursor:
this fails to process 'LyL' correctly, for example, as the second 'L'
doesn't move the cursor.
