For those not on IRC: Jerry's testing passed after some minor changes. 
I've compiled/run also some programs with no regressions, but they were 
not heavily using I/O anyhow. One can thus expect the commit soon.

For Jerry: I found something else, which does not work, namely:

PAD= in the open statement works, but PAD= in the read statement seems 
to be ignored.


character(len=9) :: a = 'XXXXXXXXX'
character(len=5) :: str = 'aaaaa'
integer :: i
open(99)
write(99,'(a)',advance='NO') 'ABCD'
rewind(99)
read(99,fmt='(a5)',pad='NO',advance='YES',iostat=i) str
close(99,status='delete')
if(i == 0) stop 'ERROR'
end
