[Snowball-discuss] missing conjugations in french

[066ce286 at free.fr]

Hello,

In french, for example the verb 'parler' (to speak) ar any other 1st group verbs are conjugated as :

[I, you (singular), he/she), we, you (plural), they]
« parle parles parle parlons parlez parlent »

But stemming provinded by snowball is : 

« parl parl parl parlon parl parlent »

I suggest following patch in snowball/algorithms/french.sbl

After regenerating stem_UTF_8_french.c and recompiling dict_snowball.so against postgresql, then I have better stemming :

loxodata_text=# select to_tsvector('french','parle parles parle parlons parlez parlent');
    to_tsvector     
--------------------
 'parl':1,2,3,4,5,6
(1 row)
