[PATCH] tar: updated help

[Christophe Vidal]

Hi,

Here is a patch for tar that documents long options without a short option
in --help

Long options documented:
--overwrite
--lzma
--strip-components
--no-recursion
--to-command
--numeric-owner
--no-same-permissions

Minor reformatting is also included for alignment purposes.

Inspired by GNU tar, I am proposing not to exhaustively list all the
supported long options in the usage line, and instead replace them by a
generic [OPTIONS]... placeholder, but open to other suggestions on this.

Thanks,
Chris
