Currently, the bidi type table is global, so you cannot change it on a
buffer by buffer basis.

More importantly, I don't think it's a good idea to change the bidi
properties in such a radical way (or at all), because we don't have
the resources to investigate all of the consequences.  For example, <
is a mirrored character, so when it's between to R2L characters, it
displays as > and vice versa.  Yes, I know: you'll suggest to change
the mirroring table as well, but how far should we go? do we really
want to create our own UBA?

But it will do The Wrong Thing if < or > are parts of the buffer name
