Ron Yorston ad1b4d5882 less: add a function to detect when display is at end of file 
Add a function to package the test that detects whether enough has
been read from the file to allow a screenful to be displayed.

Also use this to determine when to display '(END)' in the status
line.  The previous code was incomplete and didn't handle truncated
lines (-S flag) properly.
