Minor fix for revert: No need to make a backup when forgetting added files.
echo foo > foo && hg add foo && hg revert foo
creates foo.orig, though foo is not changed or deleted.
#!/bin/sh
set -e
mkdir test
cd test
echo foo>foo
hg init
hg addremove
hg commit -m "1"
hg verify
hg clone . ../branch
cd ../branch
hg co
echo bar>>foo
hg commit -m "2"
cd ../test
hg pull ../branch
hg verify
hg co
cat foo
hg manifest
