Patch looks ok, but your mailer damaged it heavily.

Hi , thanks for reply , I will send them again, and this time I will check 
that mailer doesn't mess with patches.

I fixed word wrap problem.

I also want to note that my address is now maximlevitsky@gmail.com , the 
address I took recently because yahoo is only aviable via webmail
and it is not good for patches.

Thanks for reply, 

regards , Maxim Levitsky
