friendly markup names for UI: e.g. 'Markdown' not 'mdwn' (patch)

[ikiwiki] / doc / todo / inline_option_for_pagespec-specific_show__61__N.mdwn

inline could have a pagespec-specific show=N option, to say things like "10 news items (news/*), but at most 3 news items about releases (news/releases/*)".

This should eliminate the need for wikiannounce to delete old news items about releases.
