Log Message:
Fix buffer allocation in function `raw_cat'. It was possible to get a
buffer size of zero if stdout has a block size of 0.
The command `rsh <host> cat <files>' gives no output and no error.

- Allocate a minimum of BUFSIZ bytes for buffer.
- Use a static buffer if either `fstat' or `malloc' fails.
- Do the allocation once since stdout will not change block size.
