v0.9.2

• A new file opened while git is slow for another lands with its open.
  In the editor, a file git placed at once was written only at the next
  retry, a quarter second later, whenever another file's git ls-files was
  still out, so the request right after its open missed it. Opens behind a
  pending answer now share a 100 ms wait.
• A path gem's copy of a stdlib file answers alone. require "json"
  where a Bundler path: gem has its own lib/json.rb answered that copy
  and the stdlib's, ambiguous; Bundler puts a path gem's lib/ ahead of
  the stdlib as surely as an installed gem's, so it is now resolved. A copy
  in the checkout's own lib/, test/ or spec/ is still listed beside
  the stdlib's, since those are only guessed to be on the load path.
• A --refs miss on a name reached through an ancestor says where it
  is. --refs File::NULL read as if nothing defined it; the mentions are
  listed under IO::NULL, where Ruby finds it through File < IO. The
  miss now adds "found through File's ancestor IO, it is IO::NULL" (or,
  through an alias, the name Ruby's lookup reaches). Which rows are found
  is unchanged.
