Critical issue: flag glyphs changing shape

[Patrick McCarty]

Hi Carl,

After looking through the regtest comparison for 2.13.19/2.13.20, I
noticed that flag glyphs have changed shape.  I posted a tracker issue
for this:

I assume this is related to your recent changes to the Metafont code,
but I can't claim to know why.

Can you have a look?

Thanks,
Patrick
