Ahh, now I remember. Well, the I put that in like 25 years ago ;-)

Let's assume the user write a very long line and relies on the wrapping of the text box. So the input might look like the 
first attachment. Then the user hits submit and gets just one long line (second attachment) and has to scroll one kilometre
to the right to see the full line. So there is an inconsistency between the entry form and what the user sees after the
submission. Having "wrap=hard" tells the browser to put CRLF where the wrapping in the textarea happens, so the text looks
the same during entry and after submission. If we remove the "wrap=hard", we would be back to the situation below in the two
attachments.

Opinions?
