[imp] Narrow text area field for compose in H3-4.0.4

[Joaquim Homrighausen]

Since I've been using HEAD releases for some time, I ran into some
problems (of my own making) when reverting to the H3 4.0.4 release.

A user reported that the textarea field was a very narrow 3-4 characters.

After having looked at the compose template and finding the wrap_width
setting, which was missing from my prefs.php but present in
prefs.php.dist, things started looking better.

I wonder if this, however, is what should come out when wrap_width isn't
present:

<textarea class="composebody" tabindex="7" name="message" id="message"
rows="20" cols="">

Since it's such a fundamental setting for composing messages, perhaps a
minimum or default should be present if none is configured?
