Disable auto-split lines in html-mode

[meyer . p]

Hello

I'm using html-mode on emacs.

When editing html code, the line get splitted.

Here is an exemple with dummy data :

The following line :
<a href="zefezrgfeoijego eijeogjoe geg io ijoijioj" alt="zefiojzef
zefiozefio zzefzefi ">zezef </a>

is automatically changed into :
<a href="zefezrgfeoijego eijeogjoe geg io ijoijioj" alt="zefiojzef
zefiozefio zzefzefi ">zezef </a>

Can I avoid this comportment ?

I know that I should not use too long lines but when they are splitted
when editing, this causes more differences compared to my CVS repo....
but the code remains the same...

Any help here ?
