Follow-up Comment #1, bug #27275 (project grep):
Grep 2.5.4 uses both own DFA engine and regex engine included
in GNU libc, selectively. Former supports `s' operand, but later
doesn't. According to which engine used, the result is different.
See also following thread.

Where original Grep 2.5.4 doesn't interpret GREP_USE_DFA
environment variable.
