Furthermore, in contrast to the Greek-in-Latin case, which simply produces
LaTeX error if we do not use \textgreek, Latin-in-Greek does not only work,
but is also functionally used as a transliteration system [1] (I use this
myself to insert Greek terminology).
So if we start to auto-wrap latin chars in Greek context to \textlatin, we
will break old documents.
