[Bug-wget] [PATCH v5 0/4] Make wget capable of starting downloads from a specified position.

[Yousong Zhou]

This series tries to add an option `--start-pos' for specifying starting
position of a HTTP or FTP download.  Also inclued are 2 fixes for the test
infrastructure and 3 test cases for the new option.

With the new option, a user-specified zero-based offset value can be specified,
instead of deriving it from existing file which is what --continue currently
does.  When both this option and --continue are both specified which does not
make much sense, wget will warn and proceed as if --continue was not there.

v4 -> v5

        - Reworked the description in doc with kind suggestions from Tim
          Ruehsen.
        - Disable --start-pos when WARC options are used.
        - When --start-pos and --continue are both specified, emit a warning,
          use --start-pos and disable --continue, then proceed.
        - Add 2 fixes for the test infrastructure.
        - Add 3 test cases for the new option.

v3 -> v4

        In doc/wget.texi and wget usage output, explicitly note that
        --start-pos is zero-based.

v2 -> v3

        Fix a typo and add description text for the new option into the usage
        output.  Thank Darshit Shah <address@hidden> for the suggestions.

v1 -> v2

        It was kindly pointed out by Darshit Shah <address@hidden> that
        server support for resuming download is required, so adding this into
        doc/wget.texi.
