Subject: [PATCH] Added mouse-selection feature for bookmark list buffer.
 (bookmark-bmenu-other-window-with-mouse): New function.
 (bookmark-bmenu-mode-map): Bind mouse-2. (bookmark-bmenu-list,
 bookmark-insert-location, bookmark-bmenu-hide-filenames): Put text property
 on bookmarks. (bookmark-bmenu-show-filenames): Remove text property from
 white spaces generated by `move-to-column'. (bookmark-bmenu-bookmark): Use
 `buffer-substring-no-properties' instead of `buffer-substring'.
