Description

New version, with some bugfixes as noted in NEWS from the tarball:

* Noteworthy changes in release 2.9 (2011-06-21) [stable]

** Bug fixes

  grep no longer clobbers heap for an ERE like '(^| )*( |$)'
  [bug introduced in grep-2.6]

  grep is faster on regular expressions that match multibyte characters
  in brackets (such as '[áéíóú]').

  echo c|grep '[c]' would fail for any c in 0x80..0xff, with a uni-byte
  encoding for which the byte-to-wide-char mapping is nontrivial.  For
  example, the ISO-88591 locales are not affected, but ru_RU.KOI8-R is.
  [bug introduced in grep-2.6]

  grep -P no longer aborts when PCRE's backtracking limit is exceeded
  Before, echo aaaaaaaaaaaaaab |grep -P '((a+)*)+$' would abort.  Now,
  it diagnoses the problem and exits with status 2.
