Bug #15267: File.basename + File.extname does not restore the original name

----------------------------------------
Related to #15224, I found the case `File.basename(name, '.*')+File.extname(name) == File.basename(name)` is not true.

```ruby
name = 'file.'
File.basename(name, '.*') #=> "name"
File.extname(name) #=> ""
```

Both do not contain the last dot.

basename(1) seems to result in the base name with the dot, when stripping a wildcard suffix.

```
$ basename name. '.*'
name.
```
