I'm having problem with french dictionaries.  Loading an ispell affix
file with apostrophes does not work.  The file comes from the ifrench
(french dict for ispell) debian source package at
http://packages.debian.org/sid/ifrench

Here's the session excerpt:

------------------------------------------------------------------------
Welcome to psql 8.3.3, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit

dockee=# select plainto_tsquery('custom_french', 'bug');
ERROR:  syntax error at line 158 of affix file
"/usr/share/postgresql/8.3/tsearch_data/ispell_french.affix"

dockee=# show lc_ctype ;
  lc_ctype
-------------
 en_US.UTF-8
(1 row)

dockee=# show client_encoding;
 client_encoding
-----------------
 UTF8
(1 row)

dockee=# show server_version;
 server_version
----------------
 8.3.3
(1 row)
------------------------------------------------------------------------


The 'custom_french' text configuration is defined as below:

------------------------------------------------------------------------
CREATE TEXT SEARCH CONFIGURATION public.custom_french ( COPY =
pg_catalog.french );

CREATE TEXT SEARCH DICTIONARY french_ispell (
    TEMPLATE = ispell,
    DictFile = ispell_french,
    AffFile = ispell_french
);

ALTER TEXT SEARCH CONFIGURATION custom_french
    ALTER MAPPING FOR
        asciiword,
        asciihword,
        hword_asciipart,
        word,
        hword,
        hword_part
    WITH french_ispell ;

ALTER TEXT SEARCH CONFIGURATION custom_french
    DROP MAPPING FOR
        url,url_path,sfloat,float,file,int,version;
------------------------------------------------------------------------


Line 158 of file ispell_french.affix corresponds to the first flag
definition that triggers a prefix with an apostrophe, it's the line
below "flag *N"

------------------------------------------------------------------------
flag *D:                        # dé: défaire, dégrossir
    .               >   dé

flag *N:                        # élision d'une négation
    [aàâeèéêiîoôuh] >   n'      # je n'aime pas, il n'y a pas
------------------------------------------------------------------------

Maybe apostrophes in ispell affix files are simply not supported?  I
can't find a mention of this limitation in the documentation at
http://www.postgresql.org/docs/8.3/static/textsearch-dictionaries.html

When commenting out the offending flag definitions, the affix file
loads successfully.  Thanks in advance for helping me resolve this
problem.
