Read permission request kind needs better clarification between directory and file reads

If my working directory, contains a "." in the name there is not a clear way to distinguish between file and directory reads.

For example, I can get requests like this:

Kind: read
Path: q:\src\workspace.net

In this case path is a directory but also looks like a file name. It would be nice if all directory paths always ended with path separator to clarify.

Start by locating the read permission request handling and the code that formats its Path value. Update directory paths to include a path separator while preserving file paths, then verify that requests distinguish directory and file reads as described.
