[tex-hyphen] Adding support for Hebrew (UNIV: XeTeX, NOT XeLaTeX)

[Philip Taylor]

Trying to add support for Hebrew to TeX Live 2016, as I find I have to do each 
time a new release comes out, I have, after much trial-and-effort, succeeded in 
at least getting \language {hebrew} to be accepted without complaint.  However, 
looking at the (incredibly voluminous) output from TLMGR GUI Actions: Rebuild 
all formats, after iinvoking TLMGR generate language --rebuild-sys from the 
command line, I noticed that there was something (several things, really) about 
my "hyph-he.tex" file that caused problems.  These seemed to consist of 
"non-letter" and "duplicate pattern" :

(c:/TeX/Live/texmf-local/tex/generic/hyph-utf8/patterns/hyph-he.tex
! Nonletter.
l.16 ן
       1
! Duplicate pattern.
l.28 ×°1
        
! Duplicate pattern.
l.30 ײ1
        
! Nonletter.
l.31 ײַ
        1
! Nonletter.
l.59 מּ
        1
))
 ) )

so I simply removed the offending lines from the file. But I have a number of 
questions :

1) Why do I have to use the TLMGR GUI to perform a "Rebuild all formats" when I 
have already used the command-line and requested "generate language 
--rebuild-sys" ?

2) Why are the diagnostics in crypto-speak and not in Unicode ?  I can make no 
sense of (e.g.,) "! Nonletter.  l.59 מּ" whatsoever, nor can I correlate it 
with line 59 of "hyph-he.tex"

3) Is it any way possible to suppress all the "non-error" messages in the TLMGR 
GUI transcript so that one can see the errors at a glance, or at the very least 
could all the errors be concatenated and appended ?

4) What is actually /wrong/ with my original "hyph-he.tex" (attached)

5) Why is Hebrew not natively supported by TeX Live ?  It is hardly a minority 
language.
