[PATCH] HISTTIMEFORMAT should not be set while running existing histexp.tests

[Bradley M. Kuhn]

Attached please find a small patch that makes sure HISTTIMEFORMAT is not
set when the histexp.tests run.  I use HISTTIMEFORMAT myself, and this
causes the tests to incorrectly fail.  This fix merely unsets it before
the tests are run.  Also fixed are the test output, since the line
numbers changed.

histexp.tests
 If it is, the test output is not correct.  This change unsets it before
 tests are run.
