repair: use rawvfs when copying extra store files
If we use the normal vfs, store encoding will be applied when we
.join() the path to be copied. This results in attempting to copy
a file that (likely) doesn't exist. Using the rawvfs operates on
the raw file path, which is returned by vfs.readdir().
Users at Mozilla are encountering this, as I've instructed them to
run `hg debugupgraderepo` to upgrade to generaldelta. While Mercurial
shouldn't deposit any files under .hg/store that require encoding, it
is possible for e.g. .DS_Store files to be created by the operating
system.

hg-ssh - a wrapper for ssh access to a limited set of mercurial repos
To be used in ~/.ssh/authorized_keys with the "command" option, see sshd(8):
command="hg-ssh path/to/repo1 /path/to/repo2 ~/repo3 ~user/repo4" ssh-dss ...
(probably together with these other useful options:
no-port-forwarding,no-X11-forwarding,no-agent-forwarding)
This allows pull/push over ssh from/to the repositories given as arguments.
If all your repositories are subdirectories of a common directory, you can
allow shorter paths with:
command="cd path/to/my/repositories && hg-ssh repo1 subdir/repo2"
You can use pattern matching of your normal shell, e.g.:
command="cd repos && hg-ssh user/thomas/* projects/{mercurial,foo}"
You can also add a --read-only flag to allow read-only access to a key, e.g.:
command="hg-ssh --read-only repos/*"
