Yes

Yes.

Interestingly ldd suggests it is still linked to libncurses but I think
that is via libreadline - confused me for a few minutes.

$ ldd /usr/bin/hivexsh
	linux-gate.so.1 =>  (0x00884000)
	libhivex.so.0 => /usr/lib/libhivex.so.0 (0x008c3000)
	libreadline.so.6 => /lib/libreadline.so.6 (0x00a27000)
	libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0x00110000)
	libncurses.so.5 => /lib/libncurses.so.5 (0x00e2e000)
	/lib/ld-linux.so.2 (0x00323000)
	libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0x00b43000)

$ ldd /lib/libreadline.so.6
	linux-gate.so.1 =>  (0x0025f000)
	libncurses.so.5 => /lib/libncurses.so.5 (0x00ec3000)

	/lib/ld-linux.so.2 (0x005fe000)

$ strings /usr/bin/hivexsh | grep readline
