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/bash
. $(dirname $0)/common.sh
hg svn verify
exit $?
