Fix bundle repos to use an index tuple consistent with revlogng
The bundle repo code was adding a field to the index tuple, which
confused the revlogng changes. This creates a new dict instead
to maintain the extra bundle info.
#!/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
