Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

when editing some file opened via ange-ftp, with a CPerl-mode, i
issued command

M-x replace-string RET
2001-12 RET
2002-01 RET

as a result, part of the line of the original file was lost, i.e. the
following lines

============================================================
<td><img width=70 height=250 src="/gif/ad/2001-12/page1.gif"></td>
<td><img width=70 height=250 src="/gif/ad/2001-12/page2.gif"></td>
<td><img width=70 height=250 src="/gif/ad/2001-12/pagesub1.gif"></td>
<td><img width=70 height=250 src="/gif/ad/2001-12/pagesub2.gif"></td>
</tr>
</table></td>

<td><table>
<tr><th>player1</th><td><img width=364 height=60 
src="/gif/ad/2001-12/player1.gif"></td></tr>
<tr><th>player2</th><td><img width=364 height=60 
src="/gif/ad/2001-12/player2.gif"></td></tr>
<tr><th>playersub1</th><td><img width=364 height=60 
src="/gif/ad/2001-12/playersub1.gif"></td></tr>
<tr><th>playersub2</th><td><img width=364 height=60 
src="/gif/ad/2001-12/playersub2.gif"></td></tr>
============================================================

(which were part of the whole buffer) became

============================================================
<td><img width=70 height=250 src="/gif/ad/2002-01></td>
<td><img width=70 height=250 src="/gif/ad/2002-01/page2.gif"></td>
<td><img width=70 height=250 src="/gif/ad/2002-01/pagesub1.gif"></td>
<td><img width=70 height=250 src="/gif/ad/2002-01/pagesub2.gif"></td>
</tr>
</table></td>

<td><table>
<tr><th>player1</th><td><img width=364 height=60 
src="/gif/ad/2002-01/player1.gif"></td></tr>
<tr><th>player2</th><td><img width=364 height=60 
src="/gif/ad/2002-01/player2.gif"></td></tr>
<tr><th>playersub1</th><td><img width=364 height=60 
src="/gif/ad/2002-01/playersub1.gif"></td></tr>
<tr><th>playersub2</th><td><img width=364 height=60 
src="/gif/ad/2002-01/playersub2.gif"></td></tr>
============================================================

(note that /page1.gif" on the first replaced line disappeared).

i'm able to reproduce this reliably: i open the file via ange-ftp, set
cperl-mode, and issue the above command, and get this buggy result.

if i open the file locally (not via ange-ftp), there's no bug.
