In version 1.4.x and 1.5-CVS the textarea's are using
an attribute that is not defined by W3C. The attribute
"wrap" may work in some browsers, but not in others.
After testing both Opera8 and the Gecko 1.8 engine
ignore the statement. Haven't looked at the further
impact on Squirrelmail, but for visual effect there are
options in CSS with "white-space: wrap | nowrap" and
"overflow: auto | scroll | hidden | visible".
