Yeah, this began to affect master now that the internal icu was bumped
to icu 49 so I've fixed it with
http://cgit.freedesktop.org/libreoffice/core/commit/?id=20c24114143d6d38774b56a142fd4ae05094308e

Latest line breaking UAX brought in some special hebrew rules, so a new
hebrew letter class got added, so, seeing as we have customized rules,
this ended up meaning that hebrew characters got totally ignored by our
rules cause they didn't know about the new character class :-)

I merged in the changes for these specific new rules to our existing
rules, which makes it work like before. Added a regression test for it,
and a README to document where our rules got derived to, and an easy
hack (https://bugs.freedesktop.org/show_bug.cgi?id=49885) to review the
changes that have accumulated to those rules to see if we even still
need customized line-break rules. And, if we do, to sync them up with
the latest icu ones, We're stale since at least 2006 on line-breaking it
appears.
