**/**/* does not match a/foo.rs (instead, it will only ever match an absolute path)

Describe your question, feature request, or bug.

The **/**/* pattern does not match a/foo.rs while git does. Similarly for **/**/**/* and so on.

If this is a bug, what are the steps to reproduce the behavior?

$ mkdir /tmp/rgbug
$ cd /tmp/rgbug
$ git init
$ echo '**/**/*' > .gitignore
$ mkdir a
$ echo test > a/foo
$ rg test
foo
1:test

If this is a bug, what is the actual behavior?

foo is shown as a search result, but it should be ignored. The output of --debug shows this line:

DEBUG|globset|globset/src/lib.rs:424: glob converted to regex: Glob { glob: "**/**/*", re: "(?-u)^(?:/|/.*/)[^/]*$", opts: GlobOptions { case_insensitive: false, literal_separator: true, backslash_escape: true }, tokens: Tokens([RecursiveZeroOrMore, ZeroOrMore]) }

The glob-to-regex conversion here appears wrong, since (?-u)^(?:/|/.*/)[^/]*$ can only ever match paths that start with a /.

If this is a bug, what is the expected behavior?

foo should have been ignored by the **/**/* pattern.
