Steps to reproduce:

  1. Run printf 'a\e\0b' | less -R

Expected result:
Less should display

ab
(END)

Actual result:
Less displays

a(END)

Problem exists in less-590 and less-661. Have not tested other versions.

is_ansi_middle(0) and is_ansi_end(0) should return FALSE.
325d4db 
Currently they return TRUE, which can cause problems when
there is a NUL char in the input file.

Related to #550.
