[tex-hyphen] A strange special case in Turkish hyphenation patterns for TeX

My contribution to the Turkish hyphenation patterns was at the end of
the 90s and mostly toward adapting it to recent encodings. I also
probably added or removed a few letters that were or weren't used in
modern Turkish.

Although I'm a native speaker, I'm not a linguist but you're right about
the curiousness of that special "-ecek" case. I've never heard of any
such special case and it doesn't make sense to me. You're also right
about the general vowel harmony rule that would dictate that there be a
similar rule for "-acak". I don't know if I'm overlooking something here
but I feel like it would be better to remove the "-ecek" special rule.

All the best,

They are both mentioned as people who participated in development of the current version of Turkish patterns. Unfortunately, Pierre MacKay passed away earlier this year so there is no way to know the original reason of this tiny little inconsistency.
