word wrapping in a long document ?!?

[William Case]

Hi;

A question born out of frustration.  I have searched the info manual
etc.  Probably, mis-reading or mis-seeing.

I have a long text document that I have opened in emacs. It is almost
completely filled with fringe indicators showing no word wrapping.  I
have word-wrapping mode toggled on.  I can make sentences wrap for a
paragraph by entering return at the end of each paragraph.

Is there a command that will travel through the entire document and add
wrapping (remove fringe indicators) wherever needed.
