    grep: Upgrade to version 2.9
    
    Release 2.9 (2011-06-21) [stable]
    Release 2.8 (2011-05-13) [stable]
    
    Bug Fixes
    ===================
    1. echo c|grep '[c]' would fail for any c in 0x80..0xff,
       and in many locales.
       E.g., printf '\xff\n'|grep "$(printf '[\xff]')" || echo FAIL
       would print FAIL rather than the required matching line.
       [bug introduced in grep-2.6]
    
    2. grep's interpretation of range expression is now more consistent with
       that of other tools.  [bug present since multi-byte character set
       support was introduced in 2.5.2, though the steps needed to reproduce
       it changed in grep-2.6]
    
    3. grep erroneously returned with exit status 1 on some memory allocation
       failure. [bug present since "the beginning"]
    
    4. grep no longer clobbers heap for an ERE like '(^| )*( |$)'
       [bug introduced in grep-2.6]
    
    5. grep is faster on regular expressions that match multibyte characters
       in brackets (such as '[áéíóú]').
    
    6. 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]
    
    7. 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.
