On second thoughts, probably safer not to prune initial slashes, in case
// is special.

 Named directories are typically home directories for users on the system.
 They may also be defined if the text after the `tt(~)' is the name
 of a string shell parameter whose value begins with a `tt(/)'.
+Note that trailing slashes will be removed from the path to the directory
+(though the original parameter is not modified).
 It is also possible to define directory names using the tt(-d) option to the
 tt(hash) builtin.
