NEEDAFFIX with both PFX and SFX

[Pablo Saratxaga]

Hello,

The walloon language has changes on the beginning of words depending on phonetic of previous word;
I implemented that with PFX rules.

Then I use various SFX rules.
For verbs I use scond level SFX rules, to decrease the number of rules.

It works quite well, however when SFX and PFX flags are used, the stem is made a valid word, despite being explicitely flagges with NEEDAFIX.
(at least is it like that in 1.7.0 version)

# "v" flag is for verbs;
# if the stem given in dic file ends in "é" it is a verb of 1st group (flag "1"),
# and it is also "stem A" of verbs (they can have several stems, but kept simple here)
# the ending "é" is stipped, but I use the "*" flag to tell this stripped stem is not a word
SFX v Y 2
SFX v   é       /1*     é       po:v
SFX v   é       /A*     é       po:v

# rules for 1st group of verbs, the ending "é" is added back; is stemA (bdjA) and past participle (p.p.) form

in case of only using SFX (eg viké/v* ); the stripped stem "vik" is correctly ignored as a valid word;
however, when using also PFX (eg: diné/iv ) the stripped stem "din" as well as "dn" are incorrectly included as valid:

$ hunspell -d x -m test.txt
diné  sp:plin st:diner
diné  st:diner po:v is:bdjA is:p.p.
diné sp:plin  st:diner po:v is:bdjA is:p.p.

dné  sp:spotch st:diner
dné sp:spotch  st:diner po:v is:bdjA is:p.p.

dinans  st:diner po:v is:bdjA is:pr. is:1pl
dinans sp:plin  st:diner po:v is:bdjA is:pr. is:1pl

dnans sp:spotch  st:diner po:v is:bdjA is:pr. is:1pl

din sp:plin  st:diner po:v   <=== wrong

dn sp:spotch  st:diner po:v <==== wrong

viké    st:viker po:v is:bdjA is:p.p.

vicans          st:viker po:v is:bdjA is:pr. is:1pl

vik

I would have expected

diné/iv* st:diner

to be equivalent to

diné/v* sp:plin st:diner
dné/v* sp:spotch st:diner

(if I do write it like that, it's ok; but that would require rewriting a thousand lines)

Is there something I am missing, or is that behaviour incorrect ?

Thanks
