Hi Eric,

i have found a small bug in speedbar which probably prevents `speedbar-vc-directory-enable-hook' to work correct or to work at all.

The line

(run-hook-with-args ....)

must be

(run-hook-with-arg-until-success ...)

because the docstring of run-hook-with-args says "...it is the best to to depend on the value returned by run-hook-with-args!..."

Otherwise the result of speedbar-vc-check-dir-p is unpredictable for all backends besides CVS, RCS and SCCS...
