[PATCH] left-fringe for speedbar

[Nick Roberts <nickrob@snap.net.nz>]

In gud.el I've made visibility of some tool bar buttons e.g the unintuitive
break and clear buttons, conditional on the fringe (these operations can be
done in the fringe, if present).  Unfortunately window-fringes uses the
selected window and not the one that determines the tool-bar, when multiple
frames are used:

    ([break]	menu-item "Set Breakpoint" gud-break
                  :enable (not gud-running)
		  :visible (not (and (memq gud-minor-mode '(gdbmi gdba))
                      (> (car (window-fringes 0))))))

This means that the extra buttons appear every time the speedbar is selected.

The speedbar is a key part of gdba for watch expressions so I'd like to put
the left-fringe back.  Are there any objections?

Nick
