grep: change default behaviour to search working directory files (BC)
With this patch, grep searches on the working directory by default
and looks for all files tracked by the working directory and greps on them.
### OLD BEHAVIOUR
$ hg init a
$ cd a
$ echo "some text">>file1
$ hg add file1
$ hg commit -m "adds file1"
$ hg mv file1 file2
$ hg grep "some"
`file2:1:some text`
`file1:0:some text`
This behaviour is undesirable since file1 is not in the current history and was
renamed as file2, so the second result was redundant and confusing.
### NEW BEHAVIOUR
$ hg init a
$ cd a
$ echo "some text">>file1
$ hg add file1
$ hg commit -m "adds file1"
$ hg mv file1 file2
$ hg grep "some"
`file2:2147483647:some text`
