• Limit option expansion during glob listing (list() and listSync()) to a
  maximum of 10,000 branches. Globs with combinatorial option expansions
  exceeding 10,000 will now throw a FormatException to prevent out-of-memory
  exhaustion. Glob.matches() uses regular expressions and is unaffected.
• Allow ** to match zero directories at the start of a pattern or following
  a separator (e.g. **/foo matches foo and a/**/b matches a/b).
