[cgreek:00266] Saving to Ibycus format

[Alexej Kryukov <basileia@xxxxxxxxx>]

I tried to save some of my Unicode documents to
Ibycus format, and I've experienced some problems.

First of all, Greek ano teleia (#x0387) is not
converted from Unicode.

Second, many redundant pairs of \eng{greek} ... \begin{greek}
are produced. The algorithm used removes these pairs
on line breaks, but not on common punctuation characters, 
like period or comma.

Also, I don't understand the following code:

(while (re-search-forward "\\ci" nil t)
...

\\ci means "an Indic character", isn't it? How it is possible
that it works for Greek?
