faq-bot v0.2.9

Fixed

• Restore the 0.2.7 regex screen. The adjacency rework in 0.2.8 refused rules that are provably
  fast, including the two commonest shapes an operator writes: a capture between two unbounded
  quantifiers (^\s*(.*)\s*$, .*(\d+).*), each measured at 0.0 ms against a full 1000-character
  input. A refused rule is only logged, so those installs stopped answering with no other symptom. The
  same rework also let a*(b)*a*a*$ through, at 1.3 s against 301 characters, because a group that can
  match empty was treated as breaking the adjacency run when it actually joins the quantifiers on
  either side of it.
  The screen is back to the 0.2.7 behaviour, which refuses (a+)+, .*.*.* and (a?){40} and the
  ambiguous repeated alternations 0.2.7 added. The shapes 0.2.8 aimed at, a run of adjacent unbounded
  quantifiers spelled with groups or with overlapping character classes, are accepted again; they need
  a screen that models a group's width and nullability, which this one does not.
