There's not a simple solution to this without doing a rewrite. The URL for login for example is a function of multiple files working together located in different folders and sub folders, not a path to a specific folder that contains all the files and functions to make that particular page work. That is why the function is called as it is.
Google will index it just fine and people doing a search will be looking at the page title and meta description, not the link. If they want to bookmark the login link for example, they can go to that page and bookmark it.
