I think I've a few ideas how to fix the problem with deleted files.

First idea is:

1. checkout a new revision into a temporary directory
2. create patch between the current checkout in $SRCDEST and the
checkout from 1.
3. replace the checkout in $SRCDEST with the temporary checkout from 1.
4. apply the patch from 2. to the sources in $srcdir
5. update .svn of the checkout in $srcdir using the one from $SRCDEST

The temporary checkout could by avoided if the patch was created using
"svn diff" but that would probably download the changes twice.

Second idea is to do the update the other way for svn:
1. run "svn update" on the checkout in $srcdir
2. replace the sources in $SRCDEST with "svn export" from $srcdir
3. copy .svn from checkout in $srcdir to the sources in $SRCDEST
effectively making it a valid checkout

The last idea:
Log deleted files from the "svn update" output and then delete them
manually. However, I'm afraid of such approach, because it would break
if the update output changed.
