tramp (2.0.36); FreeBSD 5.2.1 tramp chunk-size bug test result

[It's me FKtPp ;)]

Enter your bug report in this message, including as much detail as you
possibly can about the problem, what you did to cause it and what the
local and remote machines are.

If you can give a simple set of instructions to make this bug happen
reliably, please include those.  Thank you for helping kill bugs in
TRAMP.

Another useful thing to do is to put (setq tramp-debug-buffer t) in
the ~/.emacs file and to repeat the bug.  Then, include the contents
of the *tramp/foo* buffer and the *debug tramp/foo* buffer in your bug
report.

--bug report follows this line--

AT FIRST, FUNCTION TEST:

(with-temp-buffer
    (let ((bytes 1000)
      (proc (start-process (buffer-name) (current-buffer) "wc" "-c")))
      (process-send-string proc (make-string bytes ?x))
      (process-send-eof proc)
      (process-send-eof proc)
      (accept-process-output proc 1)
      (goto-char (point-min))
      (re-search-forward "\\w+")
      (message "Bytes sent: %s\tBytes received: %s" bytes (match-string 0))))

If I change (bytes 1000) to (bytes 500), and number less then 500, it
will always return equal values.

If the run "C-u 100 C-x C-e" on this function(unchanged version), and
it return this values:

"Bytes sent: 1000       Bytes received: 
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

and up to (bytes 6023), this function will do the same as (bytes
1000), the return value have two condition. one is the above format,
the other is euqal value like this:

Bytes sent: 6023        Bytes received: 6023

But it I change it to (bytes 6024) and any values biger than 6023, it
still return above format messages, but sometimes it will run into a
new condition --- back-trace :P

Debugger entered--Lisp error: (search-failed "\\w+")

  (with-temp-buffer (let (... ...) (process-send-string proc ...)

received: %s" bytes ...))))

And this time I also tested the tramp-chunksize value. the result is:

If tramp-chunksize below "6450", every thing will be okay. or
sometimes it will frozen on saving file (su:address@hidden method).
