Re: [PROPOSAL] Improvements of Hunspell dictionaries support

Hello again!

Patches
=======

I had implemented support for FLAG long, FLAG num and AF parameters. I
attached patch to the e-mail (hunspell-dict.patch).

This patch allow to use Hunspell dictionaries listed in the previous
e-mail: ar, br_fr, ca, ca_valencia, en_ca, en_gb, en_us, fr, gl_es,
hu_hu, is, ne_np, nl_nl, si_lk.

The most part of changes was in spell.c in the affix file parsing code.
The following are dictionary structures changes:
- useFlagAliases and flagMode fields had been added to the IspellDict
struct;
- flagval array size had been increased from 256 to 65000;
- flag field of the AFFIX struct also had been increased.

I also had implemented a patch that fixes an error from the e-mail
http://www.postgresql.org/message-id/[email protected]
This patch just ignore that error.

Tests
=====

Extention test dictionaries for loading into PostgreSQL and for
normalizing with ts_lexize function can be downloaded from
https://dl.dropboxusercontent.com/u/15423817/HunspellDictTest.tar.gz

It would be nice if somebody can do additional tests of dictionaries of
well known languages. Because I do not know many of them.

Other Improvements
==================

There are also some parameters for compound words. But I am not sure
that we want use this parameters.
