At least on my 32 bit box, tab completion works fine. But, the d_off of
LLONG_MAX comes from btrfs_readdir(). Git had a feature where it would
loop infinitely over a directory in some cases and this was my
workaround.
This should be fixed in git by now, so I can drop it if that really is
causing problems in bash.
