Цитирую /usr/share/doc/grep-2.14/NEWS:

* Noteworthy changes in release 2.11 (2012-03-02) [stable]

** New features

  If no file operand is given, and a command-line -r or equivalent
  option is given, grep now searches the working directory.  Formerly
  grep ignored the -r and searched standard input nonrecursively.
  An -r found in GREP_OPTIONS does not have this new effect.
