-This function resolves the true case of each element in the
-path and returns the case-sensitive path.
+C<guestfs_case_sensitive_path> attempts to resolve the true case of
+each element in the path. It will return a resolved path if either the
+full path or its parent directory exists. If the parent directory
+exists but the full path does not, the case of the parent directory
+will be correctly resolved, and the remainder appended unmodified. For
+example, if the file C<\"/Windows/System32/netkvm.sys\"> exists:
 
-Thus C<guestfs_case_sensitive_path> (\"/Windows/System32\")
-might return C<\"/WINDOWS/system32\"> (the exact return value
-would depend on details of how the directories were originally
-created under Windows).
