----------------------------+-----------------------------------------------
 In versions of Sage up to 4.3.2, the following worked as expected:

 {{{
 >./sage
 ----------------------------------------------------------------------
 | Sage Version 4.3.2, Release Date: 2010-02-06                       |
 | Type notebook() for the GUI, and license() for information.        |
 ----------------------------------------------------------------------
 sage: _?
 [...]
 sage: _
 ''
 sage: _
 ''
 }}}

 However, with Sage 4.3.3, it has stopped working:

 {{{
 ----------------------------------------------------------------------
 | Sage Version 4.3.3, Release Date: 2010-02-21                       |
 | Type notebook() for the GUI, and license() for information.        |
 ----------------------------------------------------------------------
 sage: _?
 [...]
 sage: _
 ''
 sage: _
 <bound method NullTranslations.ugettext of <gettext.NullTranslations
 instance at 0x4b1a680>>
 }}}

 For some things, the history works as expected, but for others it does
 not.  To me it appears that it is "simple" things, e.g. above, the empty
 expression, or simple expressions like "3+4" where it does not work
 anymore, but for more complex things (e.g. if you call a function that
 returns something), "_" still does what you would expect it to do.

 This bug still exists in Sage 4.3.5.
