What is a word?
	To me, a 'word' it any string containing no blank or hyphen. Thus, at the end
of a line, 'high-speed car' can be broken into 'high-' and 'speed car', or into
'high-speed' and 'car'.
But, if I write an equation 'x=a+b-2-aaa-bbb+ccc', I want it to remain whole.
OpenOffice insists on breaking it (at the end of a line) at every '/', '+' or
'-', even if I use an endash, emdash, or a 'real' minus sign  (unicode 2212)
instead of a hyphen.
	Same problem for a symbol as simple as C^-1: it can be broken into 'C' at the
end of a line and the exponent on the next line. Yes, I can use a formula to
keep the symbol whole, but that's clumsy, and it introduces extra space around
the symbol.
	Solution: OpenOffice should have a customizable list of 'hyphenable' characters
(other than space), With an empty list, any string without space would be
considered an unbreakable 'word' (except, of course, if it exceeded a whole line)
