Problem with "yes_or_no" and newline character

[Michael Goffioul]

Hi,

When executing

   eval('yes_or_no("Close ? ")')

the "yes_or_no" never terminates, because the newline character
is appended to the string returned by interactive_input, which is not
expected by yes_or_no. When doing the call within "eval", "line_editing"
is set to false, resulting in "gnu_readline" calling "octave_fgets" instead
of "command_editor::readline". The problem is that "octave_fgets" includes
the newline character, while "command_editor::readline" does not.

Using "octave_fgetl" would probably solve the problem (cannot test for
the moment).

Michael.
