git test failure: t9903-bash-prompt.sh on darwin8

[David Fang]

Hi,
 	I'm seeing a test failure with git-1.8.4 on powerpc-darwin8:

[11:00:56] t9903-bash-prompt.sh ...............................
not ok 13 - prompt - interactive rebase
not ok 14 - prompt - rebase merge

Details here:

The odd thing is that when I run the test t9903 interactively, 
post-mortem, it passes -- I am unable to reproduce the failure outside of 
the unprivileged build environment.
Interactively, the test always passes regardless of my interaction shell: 
csh, sh-2.0, bash-4.2.  (Noninteractive test happens to use bash-2.0.)

So I force the test to halt immediately upon failure to examine the 
temporary trash directory, and the difference between actual/expected:

What could cause the results to differ between by interactive and 
non-interactive testing of t9903?  Is there a real problem?
