Resolve issues with rm * globbing (#3516)
Using the `*` wildcard should not attempt to delete files with a leading dot
unless the more explicit `.*` is used. `rm *` should also not attempt to delete
the current directory or its parent directory (`.` and `..`). I have resolved
this bug as well in a less satisfactory way. I think it may be the case that we
can only disambiguate the `.` and `..` path segments by using `Path::display`.
Here is a short list of alternatives that I tried:

- `Path::ends_with()` can detect `/..` but not `/.`.
- `Path::iter()` and `Path::components()` leave out `/.`.
- `Path::file_name()` normalizes `/.` to the parent component's file name.

Fixes #3508
