canonicalize() splits its input on the separator and runs each token
through os.path.realpath(). os.path.realpath('') returns the current
working directory, so canonicalize('') and canonicalize(None) wrongly
produced the cwd instead of an empty string, and a stray separator (for
example "a,,b") injected a spurious cwd entry into the result.Skip empty tokens alongside the existing unexpanded-variable skip so only real paths are canonicalized.
