editor: add a small changectx cache Reverts including a lot of files create many actions like: R bar (from trunk/bar:4343) For each of these files, an open_file() call is made and the parent mercurial revision is loaded to detect copies in issamefile(). This results in a big slowdown, easily reduced by caching the changectx.

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

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