hexl-insert-hex-char in hexl-mode delete a wrong line

[ds]

hello
     There is a interesting thing when i edit a binary file
  The file in hexl-mode like this :
   0800 7508 b000 e9e3 0000 0090 8b45 088b
   80ec 1d00 0089 45fc 837d fc00 750a b000
   e9c9 0000 008d 7600 8b45 fc8b 8028 0600
   then you modify the forth hexl char 08  to  e8  using  
hexl-insert-hex-char function . emacs still show there is no wrong.
   But when you use C-x C-s to save this buffer ,then you open it again
you will find the second line : 80ec 1d00 0089 45fc 837d fc00 750a b000 
disappear. I don't kown why .

Could you please post a *precise* test case for this bug?  The test
case should start with `emacs -q', so that your .emacs file does not
affect it, and it should show exactly what text to put in the buffer,
what commands to execute, and how and where to click.  Also please say
exactly what incorrect results you get.

Please read the Bugs section in the Emacs manual, which provides
guidelines on how to write a bug report to give us the
necessary information so we can fix the bug.
