color: change color of grep.rev label

GNU grep uses green for line numbers as we do, but I sometimes get a

and revisions and don't know which one is which.

A different colour can help.

 Fix_Wdir(): test that passing wdir() t -r flag does greps on the
 files modified in the working directory
 
   $ cd a
   $ echo "abracadara" >> a
   $ hg add a
   $ hg grep -r "wdir()" "abra"
   a:2147483647:abracadara
 
   $ cd ..
 
 Change Default of grep by ui.tweakdefaults, that is, the files not in current
 working directory should not be grepp-ed on
 
   $ hg init ab
   $ cd ab
   $ cat <<'EOF' >> .hg/hgrc
   > [ui]
   > tweakdefaults = True
   > EOF
   $ echo "some text">>file1
   $ hg add file1
   $ hg commit -m "adds file1"
   $ hg mv file1 file2
 
 wdir revision is hidden by default:
 
   $ hg grep "some"
   file2:some text
 
 but it should be available in template dict:
 
   $ hg grep "some" -Tjson
   [
    {
     "date": [0, 0],
     "lineno": 1,
     "node": "ffffffffffffffffffffffffffffffffffffffff",
     "path": "file2",
     "rev": 2147483647,
     "texts": [{"matched": true, "text": "some"}, {"matched": false, "text": " text"}],
     "user": "test"
    }
   ]
 
   $ cd ..
 
 test -rMULTIREV with --all-files

   um:0:unmod
   um:1:unmod
   $ hg grep -r "0:2" "unmod" --all-files um
   um:0:unmod
