editor: convert two assertions in apply_textdelta() into raising an IOError I noticed these in the traceback filed as issue2261 in the Mercurial bug tracker. We should always fail in cases where the Subversion server gives us invalid data, so using assertions is wrong.

#!/bin/sh
. $(dirname $0)/common.sh

for b in `hg branches -aq` ; do
    hg co $b || break
    echo verifying $b
    hg svn verify
done
