ignore: remove .hgignore from ignore list if nonexistent Previously we would always pass the root .hgignore path to the ignore parser. The parser then had to be aware that the first path was special, and not warn if it didn't exist. In preparation for making the ignore file parser more generically usable, let's make the parse logic not aware of this special case, and instead just not pass the root .hgignore in if it doesn't exist.
