    [-- Attachment #1: Type: text/plain, Size: 2651 bytes --]
    
    See attached screenshot from `emacs -Q' followed by M-x speedbar.
    
    Some of the file names are followed by a codepoint 35 character (`#')
    that is displayed as a blue matrix of tiny 0s and 1s.  Other file names
    have no such character after them.  (Not shown: read-only files have
    instead a yellow padlock icon following the file name.)
    
    `C-u C-x =' on that character gives this info:
    
                 position: 21143 of 44023 (48%), column: 18
                character: # (displayed as #) (codepoint 35, #o43, #x23)
        preferred charset: ascii (ASCII (ISO646 IRV))
    code point in charset: 0x23
                   script: latin
                   syntax: . 	which means: punctuation
                 category: .:Base, a:ASCII, l:Latin, r:Roman
                 to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
              buffer code: #x23
                file code: #x23 (encoded by coding system iso-latin-1-dos)
                  display: by this font (glyph code)
        uniscribe:-outline-Courier New-normal-normal-normal-mono-17-*-*-*-c-*-iso8859-1 (#x06)
    
    Character code properties: customize what to show
      name: NUMBER SIGN
      general-category: Po (Punctuation, Other)
      decomposition: (35) ('#')
    
    There are text properties here:
      display              [Show]
      rear-nonsticky       [Show]
    
    However, where the text copied above shows "# (displayed as #)", what
    I actually see in buffer *Help* is "# (displayed as [])", where `[]'
    is that blue binary matrix char display.
    
    Seems like a bug of some kind.  `C-h m' says that character `#' after
    a file name indicates that the file has been compiled:
    
    "Files with a `#' or `!' character after them are source files that
     have an object file associated with them.  The `!' indicates that the
     files is out of date.  You can control what source/object associations
     exist through the variable `speedbar-obj-alist'."
    
    So it seems that the bug is that the `#' char is displayed wrong (in
    both speedbar and `C-u C-x =' output).
    
    (A second comment about the speedbar display, in passing: Why does it
    use a different face for mouseover from the default face for this
    elsewhere, `highlight'?  If a user has gone to the trouble of
    customizing face `highlight', why would that not be used here also?)
