I spotted something that could be the subject of your report, and it
certainly is a bug, if not _the_ bug: the column of the cursor
position is not preserved (it is off by one).

So I went ahead and fixed that bug.  Please try the latest development
version and see if it fixed your problem; then I will close the bug
report.  If the bug is still there, please do provide the details I
requested in my previous message.

Thanks.
