That's the correct value.

Could you please now run `set' as a grep command, i.e.:

  M-x grep RET C-a C-k set RET

and send all lines that match "grep" (e.g. by using `M-x occur RET grep'
on the output buffer).  For instance, I have the following
grep-related environment variables in the output buffer:

  GREP_COLOR='01;31'
  GREP_COLORS='mt=01;31:fn=:ln=:bn=:se=:ml=:cx=:ne'
  GREP_OPTIONS='--color=auto --color=auto'
  TERM=emacs-grep

with whose I get the correct match highlighting running GNU grep 2.6.3.
