[arch-dev-public] [signoff] grep-2.7-1

[Allan McRae]

Upstream update.  This is the biggest point of interest:

   grep now diagnoses (and fails with exit status 2) commonly mistyped
   regular expression like [:space:], [:digit:], etc.  Before, those were
   silently interpreted as [ac:eps] and [dgit:] respectively.  Virtually
   all who make that class of mistake should have used [[:space:]] or
   [[:digit:]].  This new behavior is disabled when the POSIXLY_CORRECT
   environment variable is set.

Signoff both,
Allan
