[PLUG] Emacs: Setting Line Length for .txt Files

[Rich Shepard]

   My emacs wraps lines of .txt files at column 72. However, sometimes (and
all too often) it will wrap a line at column 46 or so and there's no way I
can fill that line so it remains filled with I re-format the paragraph with
M-q.

   Looked on the Web (including emacswiki) and in ~/.emacs for insight on
setting the line length but did not find anything. Please provide a pointer
to setting line wrap column for text files.
