  1243         This function is called when we're stripping revision minlink and

  1244         its descendants from the repository.

  1245 

  1246         We have to remove all revisions with linkrev >= minlink, because

  1247         the equivalent changelog revisions will be renumbered after the

  1248         strip.

  1249 

  1250         So we truncate the revlog on the first of these revisions, and

  1251         trust that the caller has saved the revisions that shouldn't be

  1252         removed and that it'll readd them after this truncation.
