Not Zed 2f07bc4e16 ** See bug #53258.
2004-02-06  Not Zed  <NotZed@Ximian.com>

        ** See bug #53258.

        * em-format-html-display.c (efhd_find_handler): force any bonobo
        handler types to always be inline, even attachments.

        * em-format.c (em_format_is_inline): use handler flags for special
        cases, removing all hard-coded types.

        * em-format.h (EMFormatHandler): add a flags field, so far a flag
        to set default inline viewing of the content.

2004-02-06  Not Zed  <NotZed@Ximian.com>

        * em-folder-properties.c: include string.h to kill warning.

        ** See bug #53627.

        * em-folder-view.c (emfv_popup_mark_junk): changed to work like
        delete does, jumping to the next message if required, and marking
        things immediately, then queuing up the junk marking job if
        required.

        * mail-ops.c (mail_mark_junk): ugh, this stuff totally can't go
        accessing messagelist from another thread!!!!  Changed so this
        code only does the junk reporting, not setting flags.  UGH!  It
        should be doing this implictly on the folder when you set the
        flags, or at least when you sync the folder!!!  Changed ot use the
        queued thread.

        * message-list.c (find_next_undeleted): changed to find
        next-unhidden, i.e. junk as well as deleted, if we're in
        hide-deleted mode.
        (build_tree): always call find_next_undeleted if we have a cursor.
        (build_flat): same.
