Test for showing working of allfiles flag

  $ hg init sng

  $ echo "unmod" >> um
  $ hg ci -A -m "adds unmod to um"
  adding um
  $ echo "something else" >> new

  adding new
  $ hg grep -r "." "unmod"
  [1]
  $ hg grep -r "." "unmod" --all-files
  um:1:unmod

With --all-files, the working directory is searched by default

  $ echo modified >> new
  $ hg grep --all-files mod
  new:modified
  um:unmod

 which can be overridden by -rREV

  $ hg grep --all-files -r. mod
  um:1:unmod

commands.all-files can be negated by --no-all-files

  $ hg grep --config commands.grep.all-files=True mod
  new:modified
  um:unmod
  $ hg grep --config commands.grep.all-files=True --no-all-files mod
  um:0:unmod

--diff --all-files makes no sense since --diff is the option to grep history

  $ hg grep --diff --all-files um
  abort: --diff and --all-files are mutually exclusive
  [255]

but --diff should precede the commands.grep.all-files option

  $ hg grep --config commands.grep.all-files=True --diff mod

Fix_Wdir(): test that passing wdir() t -r flag does greps on the

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

  > [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],
    "file": "file2",
    "line_number": 1,
