Thanks for attempting a patch.  However, the commit message is
unconventionally formatted; did you use 'git send-email' to send your
patch, as suggested in HACKING?  We would have to amend the message to
get rid of the 'Hi all,' line, as well as the unusual 'Subject:' line
after a sign-off.

This patch fails 'make syntax-check', because it used TABs.  Also, we
tend to use (ret < 0), not (0 > ret), even though they are equivalent.

Would you mind resubmitting to touch up those issues?
