The Impossibility of Double Gallows

[VViews]

So JKP are you saying the slant is more important than the presence/absence of the descending tail?
Sometimes there is a tail but not much or no slant. Sometimes there is a slight slant but no tail. 
I'm now completely confused about m and z.

Edit: nablator I forgot about the g character, but I guess now we can add it into the mix of characters that barely differ from m.
