[PATCH] improve surfraw subcommands list

[Marc Chantreux <eiro@xxxxxxxxx>]

hello people,

i wrote this patch for the _surfraw completion, it

    * add bookmarks support
    * remove the header from the final list

i don't know if it's good enough to be merged but
bookmark support is very useful so this is my proposal.
any review will be warmly welcome.

regards,
marc
