if an app is doing malloc(0), it is broken.  i'm really not worried at all 
about detecting OOM state.  my real world experience thus far has shown no 
actual problems with this behavior.  so unless you have some actual examples 
where this behavior "harms" u-boot, i say we merge the OP's patch.

it seems it fails to rewrap quoted lines and then when other people reply, 
their clients arent able to recover thus screwing it up even more.  pick any 
msg from you in this thread.  like this one:
