Plural forms for Slovak (SK) language

[Peter Slacik]

Hi "he"s (or maintainers of GNU gettext, I'm here the "she" according to 
the Introduction 
<http://www.gnu.org/software/gettext/manual/html_chapter/gettext_1.html#SEC1>),


last few months I'm playing a little bit with poEdit and I finally came 
across the definition of the plural forms field (10.2.5 Additional 
functions for plural forms 
<http://www.gnu.org/software/gettext/manual/html_chapter/gettext_10.html#SEC150>).

I represent the Slovak language population and I'd like to suggest 
different form of the "Plural-Forms:" definition for Slovak language.

I'm reading that:

   Three forms, special cases for numbers ending in 1 and 2, 3, 4,
   except those ending in 1[1-4]
       The header entry would look like this:

Plural-Forms: nplurals=3; \
   plural=n%10==1 && n%100!=11 ? 0 : \
          n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2;

       Languages with this property include:

       Slavic family
           Croatian, Czech, Russian, Slovak, Ukrainian 

I know that it's correct for e.g. the Czech language, but Slovak 
language behaves differently.

I've already written elsewhere, that:

   At least Slovak and Czech languages (and also Polish somehow
   similarly, but I don't know exactly; and the Russian one I don't
   remember exactly anymore, I tempt to say "like Czech") have two
   plural forms: 2,3,4 days are "dni/dny" and 5,6,7...18,19,20 days are
   "dní/dnu*".
   Difference: Slovak continues with "dní" to the infinity
   (,21,22,23...), whereas Czech followss the pattern "#1 den, #2,#3,#4
   dny, #5,#6...#9,#0 dnu*" in each decade (2#,3#...9#).
   Singular is off course one: "den(/den".

I hope I will modify the expression correctly, maybe you could bring me 
in contact with anyone who might disagree with me ;-)

   Three forms, special case for numbers one and 2, 3, 4
       The header entry would look like this:

Plural-Forms: nplurals=3; \
   plural=n==1 ? 0 : \
          n>=2 && n<=4 ? 1 : 2;

       Languages with this property include:

       Slavic family
           Slovak
