[cream] Where's the code that justifies text in normal mode?

[D. G. G. <ga...@gm...>]

Hi.

I'm trying to configure Vim so it wraps text in normal mode like Cream
does.  I mean, in Cream, when a line is longer than the width of the
screen, the line is shown in several lines without breaking words.
And I mean in normal, not in insert mode.  The file is not actually
modified, but the line is split without ever breaking a word.

It would be nice if you to have a separate Vim plugin for this, if it
doesn't exist already.  If anybody could tell me where in Cream's code
this is done, I'll make the Vim plugin myself.

Thank you in advance.
