  Changed paths:
    M lib/strict.pm

  Log Message:
  -----------
  stop directly mutating $^H in strict::bits()

This improves the code in two ways:

1. Considering strict::bits is used by B::Deparse and vars.pm as
   unofficial API, the function having this side effect is arguably
   a latent bug even if it doesn’t break those callers.

2. It is harder to follow the intended logic when the function modifies
   $^H itself but also returns a value for the caller to apply to $^H.
