You guys are all doing P5Think. The default should be autocomb, not autosplit,
and the default comb is already correct...

In that case, the -a option needs to be renamed to autocomb, rather
than autosplit as it is now.

Well, it needs to be both, really. See various discussions of
figure/ground in the psychology literature...
Pity that -F specifies the ground. Hey, I know, let's make -G the
figure, that makes about as much sense as -x vs +x, or electrons
vs positrons... :)
