Update to 4.3pl5.  Incorporate 5 official patches.

[readline43-001]
Pressing certain key sequences causes an infinite loop in _rl_dispatch_subseq
with the `key' argument set to 256.  This eventually causes bash to exceed
the stack size limit and crash with a segmentation violation.

[readline43-002]
Repeating an edit in vi-mode with `.' does not work.

[readline43-003]
When in a locale with multibyte characters, the readline display updater
will occasionally cause a segmentation fault when attempting to compute
the length of the first multibyte character on the line.

[readline43-004]
When running in a locale with multibyte characters, the readline display
updater will use carriage returns when drawing the line, overwriting any
partial output already on the screen and not terminated by a newline.

[readline43-005]
Using the vi editing mode's case-changing commands in a locale with
multibyte characters will cause garbage characters to be inserted into
the editing buffer.
