commit de4c35b8109cd06aae1e1b125dbbbca397111fd0
Author: Gary V. Vaughan <address@hidden>
Date:   Wed Nov 16 12:43:53 2011 +0700

    options-parser: provide a saner pluggable API.
    
    It's much too easy to forget that the functions you hook into
    the option parser need to return unconsumed options in the
    variable `func_run_hooks_result'; better to follow the
    convention used in the rest of bootstrap and return results in a
    variable named after the function with `_result' appended.
    * libltdl/config/options-parser (func_run_hooks): implement this
    new API.
    (Option parsing): Update the example in the header comment for
    this section to reflect the changes.
    * bootstrap (bootstrap_options_prep, bootstrap_parse_options)
    (bootstrap_validate_options): Adjust.
    * bootstrap.conf (libtool_options_prep, libtool_parse_options)
    (libtool_validate_options): Ditto.
