Create repo with unimpeachable content

  $ hg init r

  $ cd r

  $ echo 'Initially untainted file' > target

  $ echo 'Normal file here' > bystander

Clone repo so we can test pull later

Introduce content which will ultimately require censorship. Name the first

censored node C1, second C2, and so on

  $ echo 'Tainted file' > target

  $ echo 'Passwords: hunter2' >> target

  $ hg ci -m taint target

  $ C1=`hg id --debug -i`

  $ echo 'hunter3' >> target

  $ echo 'Normal file v2' > bystander

  $ hg ci -m moretaint target bystander

  $ C2=`hg id --debug -i`

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

the second head H2, and so on

  $ echo 'Tainted file is now sanitized' > target

  $ hg ci -m sanitized target

  $ H1=`hg id --debug -i`

  $ hg update -r $C2

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Can merge in revision with censored data. Test requires one branch of history

with the file censored, but we can't censor at a head, so advance H1.

  $ hg update -r $H1

  $ C3=$H1

  $ echo 'advanced head H1' > target

  $ hg ci -m 'advance head H1' target
