[PATCH] t9605: test for cvsps commit ordering bug

Import of a trivial CVS repository fails due to a cvsps bug.  Given the
following series of commits:

    timestamp             a    b    c   message
    -------------------  ---  ---  ---  -------
    2012/12/12 21:09:39  1.1            changes are done
    2012/12/12 21:09:44            1.1  changes
    2012/12/12 21:09:46            1.2  changes
    2012/12/12 21:09:50       1.1  1.3  changes are done

cvsps mangles the commit ordering (edited for brevity):

    ---------------------
    PatchSet 1
    Date: 2012/12/12 15:09:39
    Log:
    changes are done

    Members:
    	a:INITIAL->1.1
    	b:INITIAL->1.1
    	c:1.2->1.3

    ---------------------
    PatchSet 2
    Date: 2012/12/12 15:09:44
    Log:
    changes

    Members:
    	c:INITIAL->1.1

    ---------------------
    PatchSet 3
    Date: 2012/12/12 15:09:46
    Log:
    changes

    Members:
    	c:1.1->1.2

This is seen in cvsps versions 2.x and up through at least 3.7.

Ran into this recently.  No branching and no "criss cross" timestamps,
just lazy commit messages.  And it magically backed out a bug fix.

This applies on top of master.  With minor modifications I've tested it
with Eric's latest code and confirmed the bug still exists.
