Hello,

a friend of mine choked on this one when tried git for the second time
(the first time "git-repack -a -d -f" screwed his repository after the
initial checkout. This is fixed for a long time). Lucky me that he had
his libusbdriver in LD_PRELOAD which could not handle the NULL argument.
And I always thought libc would make the check before it does the system
call or does GNU/hurts not use the gnu libc?
