An additional problem is that some programs will send the last line back to 
nano with a linefeed.

`sed s:match:foo:g` does not
`grep small` does

So grep will work fine if cursor is on the next line, but a blank line is added 
if cursor is at the end of the last line. If that final blank line is removed 
from cutbuffer, then return true from send_data(). If return value is false, 
then remove last character returned from command if it is a linefeed.
