Details:

Fedora now compiles with -D_GLIBCXX_ASSERTIONS by default.  This results in an
assertion failure when exiting octave with a ctrl-D:

octave:1> /usr/include/c++/8/bits/basic_string.h:1136:
std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference
std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::back() [with _CharT =
char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>;
std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference = char&]:
Assertion '!empty()' failed.

The attached patch fixes.
