Filling and one-letter words at end of line

[Maciek Pasternacki]

I use Emacs to type texts in polish, which is my native language.  It
has a few frequently used one-letter words.  I also use both
auto-fill-mode (on by default) and, when reformatting text,
fill-paragraph and other manual filling commands.  The problem is that
these one-letter characters shouldn't occur at end of line, and fill
commands frequently places them there.  I usually place them manually
now but it's bothersome.  What is funny is that english one-letter
words (`I' and `a') are never filled at end of line.  Is there some
way to tell Emacs not to fill *any* one-letter words at end of line?

Thanks in advance,

                --japhy
