Incorect handling of .gitignore. Unable to create a file which name match against a gitignore rule

[vegaminer]

Looks like this behavior was introduced at #99

Consider the following example
.gitignore: data/locks

Now if you try to: echo some_text > data/locks/some_file.txt you'll get Permission denied
According to git documentation:

gitignore - Specifies intentionally untracked files to ignore

In my case data/locks is part of docuwiki setup, all files in this directory as well as in data/tmp and data/cache should be writable, but ignored-untracked by git repository
