Don't panic! I'm simply planning to provide a package option for a
Syriac package I'm writing to allow users to turn \emph into an alias
for \aemph within RTL environments. Slanted text is not traditional in
Syriac, but has been used more recently. It looks quite ugly. I imagine
that proper khabideh in fonts involves special shapes that are more than
the addition of slant.
