Thanks for spotting this! I had some trouble applying the patch in
this email. I got an error about "corrupt patch at line 54"

BTW: I am using this little snippet to apply patches from the mailing:

    PATCH=$(curl -L --silent https://public-inbox.org/git/xmqqr2tpcn6g.fsf@gitster.mtv.corp.google.com/raw); 
    ((printf '%s' "$PATCH" | git am -3) || (git am --abort; printf '%s' "$PATCH" | git apply)) && 
    echo && echo "Patch successfully applied"

Does this look sensible to you?

I applied the patch "manually" and the result looks good to me.
The patch looks good to me, too, but I am by no means a Perl
expert.

Thanks,
Lars
