Bzzzzt.

No, this wasn't the problem.  I had already globally modified the scan form in
h/scansbr.h (FORMAT) to deal with that particular issue.  I still got the scan
failures after making that change, which I've made to every version of MH and
NMH I've built for eons.  I should have mentioned that in the previous message.

My global change to h/scansbr.h was also to handle 5-digit numbers, like yours.

With the same exact default "FORMAT" string in h/scansbr.h, it worked fine if
I compiled it with -g/-O/no flags and it failed when I compiled it with -O2.
That's not a scan format problem  :-)
