Subject: `write' when disk full

As far as I can see, `_write' still doesn't always correctly detect a disk 
full situation (somehow I always bump on this when porting GNU `cp').  
The diffs below should fix that.

Btw, wasn't the next release supposed to have a `write' which doesn't call
`malloc' but converts `\n' into CR-LF on the fly while putting the buffer
into the transfer buffer?  `write' in the latest snapshot is still
identical to the stock v2.0 version.
