(eshell-ls-dir): Call eshell-directory-files-and-attributes with additional

argument 'integer or 'string, according to numeric-uid-gid.
(eshell-ls-file): Don't convert UID and GID to strings, as eshell-ls-dir
already did.  Enlarge max user-name string length to 14 characters.
(eshell-do-ls): Fix the long name of the -L option.
(eshell-ls-file): Enlarge default size-width to 8.
(eshell-ls-dir): Under -l, call eshell-ls-printable-size with last
argument nil.
