Re: speedbar should recognize imenu support better

[Eric Ludlam]

Hi,

  Speedbar cannot use the major mode to determine if tags will be
available because speedbar is showing/filtering files before they are
loaded, and a major-mode determined.

  Scanning `auto-mode-alist' has problems because it is both slow (it
can be very long) and those modes are often not loaded in memory, so
there is no way to determine if imenu is supported by them.

  The only automated solution would be to have a load-defs like file
find out which modes support imenu, and place that information
somewhere Speedbar can find it.
