[Bug 1456195] Re: Zero-minimum possessive groups does not match empty string

[Arne de Bruijn]

Note for wily the testcase needs to be slightly changed:

echo '"a"'|pcregrep --no-jit '("([^b"]*+(b.)?)*+")++'

(expected output is unchanged: "a")

Bug description:
  The 14.04/15.04 pcre version doesn't match some inputs with possessive
  qualfiers:

  $ echo '"a"'|pcregrep '("([^b"]*+(b.)?)*+")*+'
  $

  Earlier versions (10.04, 12.04):
  $ echo '"a"'|pcregrep '("([^b"]*+(b.)?)*+")*+'
  "a"
  $

  this is fixed with the following upstream commit (that applies cleanly
  to the 15.04 pcre):
