narrow_widen_acl: enforce narrowacl in narrow_widen (SEC)
Reviewer note: this was sent by the author as a simple bugfix, but can be
considered a security patch, since it allows users to access things outside
of the ACL, hence the (SEC) prefix.
However, this affects the `narrow` extention which is still marked as
experimental and has relatively few users aside from large companies with
their own security layers on top from what we can gather.
We feel (Alphare: or at least, I feel) like pinging the packaging list is
enough in this case.

$ hg init
$ echo a > a
$ mkdir b
$ echo b > b/b
$ hg commit -A -m "a is file, b is dir"
adding a
adding b/b
File replaced with directory:
$ rm a
$ mkdir a
$ echo a > a/a
Should fail - would corrupt dirstate:
$ hg add a/a
abort: file 'a' in dirstate clashes with 'a/a'
[255]
Removing shadow:
$ hg rm --after a
Should succeed - shadow removed:
$ hg add a/a
Directory replaced with file:
$ rm -r b
$ echo b > b
Should fail - would corrupt dirstate:
$ hg add b
abort: directory 'b' already in dirstate
[255]
Removing shadow:
$ hg rm --after b/b
Should succeed - shadow removed:
$ hg add b
Look what we got:
$ hg st
A a/a
A b
R a
R b/b
Revert reintroducing shadow - should fail:
$ rm -r a b
$ hg revert b/b
abort: file 'b' in dirstate clashes with 'b/b'
[255]
Revert all - should succeed:
$ hg revert --all
forgetting a/a
forgetting b

Long directory replaced with file:
$ mkdir d
$ mkdir d/d
$ echo d > d/d/d
$ hg commit -A -m "d is long directory"
adding d/d/d
$ rm -r d
$ echo d > d
Should fail - would corrupt dirstate:
$ hg add d
abort: directory 'd' already in dirstate
[255]
Removing shadow:
$ hg rm --after d/d/d
Should succeed - shadow removed:
$ hg add d
$ hg ci -md
Update should work at least with clean working directory:
$ rm -r a b d
$ hg up -r 0
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg st --all
C a
C b/b
$ rm -r a b
$ hg up -r 1
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg st --all
