Not Zed 27f894733e only call expunge if the folder is set. (emfb_enable_map[]): only enable 
2004-07-09  Not Zed  <NotZed@Ximian.com>

        * em-folder-browser.c (emfb_folder_expunge): only call expunge if
        the folder is set.
        (emfb_enable_map[]): only enable expunge menu item if we have a
        valid folder set.

        ** See bug #60900.

        * em-format-html.c: convert the text_inline_parts hash to be keyed
        off the partid.
        (efh_free_inline_parts): -> efh_free_cache and fix to do it.

        * em-format.c (emf_free_cache): make the inline table cache other
        info too based on partid, this frees the structure.
        (emf_clone_inlines): copy all of the cache data.
        (em_format_is_inline): use the new data structure to determine
        state.
        (em_format_set_inline): same for setting.
        (emf_multipart_signed): cache/lookup the cached part.
        (emf_insert_cache): helper to add a cache entry.
        (emf_multipart_encrypted): cache decrypted part.
        (emf_application_xpkcs7mime): same.

2004-07-08  Not Zed  <NotZed@Ximian.com>

        ** See bug #60900 (related only).

        * em-format-html-display.c (efhd_attachment_show): let set_inline
        do the redraw itself if required.  kill some dead code.

        * em-format.c (em_format_set_inline): trigger a redraw here like
        the other em_format_set methods, if the state changed.

        * em-format.c (emf_format_clone): free inline table keys & setup
        string hash table.

        * em-format-quote.c (emfq_format_attachment):
        * em-format-html-display.c (efhd_format_attachment):
        * em-format-html.c (efh_format_attachment): is_inline api changes.

        * em-format-html-display.c (efhd_attachment_show): set_inline api
        changes.

        * em-format.c (em_format_is_inline): make this use the partid
        rather than the part address as a key, which may change.
        (emf_init): make the inline talbe a string hashtable.
        (emf_finalise): free inline keys.
        (emf_clone_inlines): copy the key string.
