I have a few directories containing some files which are part of the Hg repository and some which are not. How do I list the files in the current directory which are part of the repository?

I know that 

```
hg status | grep "\? Path/To/Dir/In/Repo"

```

gets me all the files which are *not* part of the repository so I could invert the regular expression, but "hg status" also takes a long time on a large repository so a solution that doesn't need that would be ideal.

Also, if possible, the solution should not need any extensions.
