The above looks easy to grok, but the following caught my eyes.

> GIT_FLUSH=10000000000  yes                     if stdin is not a file

Is this because the int is so large that git_parse_signed() notices
that it is out of bound (hence "bogus")?

I may have suggested it, but don't think I requested ;-)

The patch text looks good.  Thanks.
