remove dabbrev--scanning-message?

["Sean O'Rourke" <sorourke@cs.ucsd.edu>]

[-- Attachment #1: Type: text/plain, Size: 497 bytes --]

When `dabbrev-expand' is invoked with many buffers and it fails
to find an expansion, there is an annoying forced pause while it
scans every buffer and emits uninteresting progress messages.  If
these messages are removed, a failed expansion is nearly
instantaneous, so I don't see any benefit to having progress
messages.  Patch attached.

	* dabbrev.el (dabbrev--scanning-message): removed.
        (dabbrev--find-expansion): remove calls.
