vfsproxy: inherit the `createmode` attribute too
It is an important part of the API when creating directory. We will need it in
the next changeset.

Introduce content which will ultimately require censorship. Name the first
censored node C1, second C2, and so on

Add a new sanitized versions to correct our mistake. Name the first head H1,

Censoring a revision that is used as delta base
-----------------------------------------------
$ cd ..
$ hg init censor-with-delta
$ cd censor-with-delta
$ echo root > target
$ hg add target
$ hg commit -m root
$ B0=`hg id --debug -i`
$ for x in `"$PYTHON" $TESTDIR/seq.py 0 50000`
> do
> echo "Password: hunter$x" >> target
> done
$ hg ci -m 'write a long file'
$ B1=`hg id --debug -i`
$ echo 'small change (should create a delta)' >> target
$ hg ci -m 'create a delta over the password'
(should show that the last revision is a delta, not a snapshot)
$ B2=`hg id --debug -i`
Make sure the last revision is a delta against the revision we will censor
$ hg debugdeltachain target -T '{rev} {chainid} {chainlen} {prevrev}\n'
0 1 1 -1
1 2 1 -1
2 2 2 1
Censor the file
$ hg cat -r $B1 target | wc -l
*50002 (re)
$ hg --config extensions.censor= censor -r $B1 target
$ hg cat -r $B1 target | wc -l
*0 (re)
Check the children is fine
$ hg cat -r $B2 target | wc -l
*50003 (re)
