I was too fast in my answer. Looking at the code, it should work
correctly. However, I think there's a bug in file.d around line
1572: the mode of the stream to check should be smm_input instead
of smm_output. Juanjo, do you confirm? (I'll commit the change
if you're OK).

I guess this bug was never triggered, because it happens to still
work with character streams.
