Could you squash you commits ?

There is also an issue when `ignoreDotFiles(false)` is called twice, could you add a failing TC and fix the code ?
`$this->ignore = $this->ignore ^ static::IGNORE_DOT_FILES;` should be `$this->ignore = $this->ignore & ~static::IGNORE_DOT_FILES;`

You need to:

- tackle the related issue I have mentioned,
- squash the commit,
- rebase,
- force push to your branch.

http://symfony.com/doc/current/contributing/code/patches.html has some more info.

As a fix, did you consider sending it to the 2.0 branch - your mention it as a BC in the commit comment but it really is a bug fix.

Thank you. I will try it.

Hasn't ```ignoreVCS(false)``` the same twice calling problem with
```$this->ignore = $this->ignore ^ static::IGNORE_VCS_FILES;```?

yep, good catch !

I mentioned it as BC, since I found no place in documentation with the information that dotFiles are ignored by default. I was also wondering that it is default behavior.

But if I only read the code, it is a 100% bug.

As soon as the PR is merged, I think we should also add a little notice in documentation like it is for ignoreVCS():

I think you should keep these changes on master. Last thing before I can merge: can you squash your commits as explained by @vicb?

I am sorry, of wasting your time... totally confused about using git. I feel a little bit squashed :-) of a the possible actions.
I hope it is squashed now. And next time I will use the issue/ticket branch I made.

That's still not good. Squashing is explained here: http://symfony.com/doc/current/contributing/code/patches.html#rework-your-patch
