FVWM: mwmborder style in 1.0.6

I'm guessing it's 1.0.6 as borders.c is a few days old.

borders.c was changed so that mwmborder no longer creates a minimal
button relief.  It's either no border or raised/sunk.

Removing mwmborder from config restores the minimal window border, but
not button border.

I changed the 2 : 2 to 1 ; 1 on my copy of borders.c to return behavior.

What's the planned way of having minimal but existing relief in buttons?
