Note: I run this on a NFS server, and I have seen tests FAIL due to 
something "strange" with NFS and deletion.

Thanks for the report.
Please tell us about the system and shell you're using.
It looks like your printf (possibly the shell's built-in one) cannot
handle usage like this:

  printf '%*s-a' 1000000 > a

As for the diff above, with the "actual" diff output lacking the
".000000000" part of the time stamp, I suspect you'll benefit from
running the test with bash. It seems like the test is somehow running
your system's diff, rather than the one just build in src/. FTR, it's
this test that is failing:

  returns_ 1 env TERM=dumb diff ---presume-output-tty --color=auto a b > out \


If you still have a problem when using bash, please include the output
of running "make check VERBOSE=YES".
