REVISION SUMMARY
  Since https://phab.mercurial-scm.org/D11387 (i.e. the same patch as
  mentioned in my previous patch), Clang has also started warning about
  `dirstate_item_set_possibly_dirty()` missing an explicit return, and
  about its use of the result of an assignment as a condition without
  using parentheses. This patch fixes that. I don't know if `return
  NULL` was the intent.
