I am seeing test failures from t4052 in 'master'. Bisecting points to
1b058bc (diff --stat: use a maximum of 5/8 for the filename part,
2012-03-01). The output from the test script looks like this:

--- expect      2012-03-26 23:41:29.688039554 +0000
+++ actual      2012-03-26 23:41:29.696039549 +0000

not ok - 8 diff: small change with long name gives more space to the name

There are a few other failures, but they all have the same mismatched
length (the output is slightly longer than expected). I know Junio won't
push out a 'master' that doesn't pass the tests for him, so I'm
wondering if some environment information like the terminal width is
leaking through the test scripts.

I haven't actually investigated any further yet, but I thought I'd first
see if anything obvious occurs to you.
