I will fix case sensitivity and low information problem of the MAP suggestion
mechanism in Hunspell.

Background:

Kevin Hendricks has implemented a wonderful new method for calculating n-gram
suggestions (MAP function). Myspell can suggest the right word for very bad
spelling (if there is no other suggestion).

[EMAIL PROTECTED] laci]$ echo Cescu | hunspell
Hunspell 1.0.8 - Magyar 1.0-RC3c
& Cescu 8 0: Ceauşescu, Ceauşescui, Ceauşescuk, Ceauşescum, Eminescu,
Ceauşescud, Eminescud, Eminescuk

CASE PROBLEM:
The algorithm has got a problem with capitalized words.

[EMAIL PROTECTED] laci]$ echo permenant | hunspell -d
/opt/openoffice.org1.9.109/share/dict/ooo/en_US
Hunspell 1.0.8
& permenant 10 0: supermen, newspapermen, empowerment, endangerment,
preferments, preferment, permanent, preferment's, permanently, impermanent
                         ---------

But MAP function doesn't suggest the right word for the capitalized version of
the bad word:

[EMAIL PROTECTED] laci]$ echo Permenant | hunspell -d
/opt/openoffice.org1.9.109/share/dict/ooo/en_US
Hunspell 1.0.8
& Permenant 10 0: Endangerment, Ferment, Fermented, Deferment's, Empowerment,
Ferment's, Ferments, Fermenting, Countermen, Weathermen

LOW INFORMATION PROBLEM:

MAP function often suggests a lot of bad suggestion, especially for
agglutinating languages, like Hungarian. Hence I've implemented an optional
off-switch for the default MAP suggestions in Hunspell 1.0.8 (NOMAPSUGS affix
parameter).

I will weight the MAP suggestions with a fast editing distance like algorithm,
and reduce the number of MAP suggestions to 3-5.

I think, target 2.0 is O.K.
