[tex-hyphen] missing hyphen points in Greek

[Claudio Beccari]

Dear hyphenators,
I am addressing thei mai to the mailng list, but I hyghlight the 
original participants in order to be sure that they receive the 
continuation of the discussion we started some weeks ago. May be Mojka 
recieves double messages; in case let me know, and I know that you are 
recieving the message as a member of the mailing list.
I just wanted to tell you that I manually upgraded the the pattern file 
for LGR encoded pattern relative to polytonic Greek.

When Dimitrios returns home, please, woulld you please send me a short 
significant text in modern polytonic Greek, written with utf-8 encoding, 
because I have no access to such kind of texts. I tested the upgraded 
polytonic patterns, I actually used a polytonic stretch of ancient greek 
text, but of course ancient Greek does not contain any neologism, modern 
names,  nor Greek renderings of foreign words.

In a day or two I start the upgrading of the ancient Greek patterns.

Cheers
Claudio
