r23752: Fix bug introduced by checkin 22920, allow large
readX. Fix from Dmitry Shatrov <dhsatrov@linux.vnet.ibm.com>.
"In send_file_readX(), if startpos > sbuf.st_size, then smb_maxcnt is set
to an invalid large value due to integer overflow.
As for me, this resulted in MS Word hanging while trying to save
a 1.5Mb document."
This isn't in shipping code.
Jeremy.
