I added a test in r372607 for your reference. It tests both `foo/..` and symlink behavior.

> Maybe only collapsing `foo/..` would be viable?

@ilya-biryukov told me that even that is not viable, in case `foo` is a symlink to a directory.

The only workable suggestion that we could come up with was adding a separate command-line option, `-normalized-header-filter`, that would normalize paths before matching the regex. It can be used by people whose project layout does not have complex symlink mazes.
