Hi,

xterm-mouse-mode (of cause, when used in a xterm window) currently does
not create mouse-motion events while dragging the mouse. Therefore,
selecting a region with mouse (press button-1 and start dragging, not
yet releasing the button) gives no visible feedback about the so far
selected region. Similar, dragging the mode-line of a window in a
splitted frame gives no feedback of the amount of window size
change. The effect of dragging the mouse becomes appearent only after
release of the button.

I prepared a patch, which greates motion-events while dragging, so that
visible feedback now is given immediately.

Further, the patch unifies the code for the default mouse protocol
encoding (enabled by "\e[?1000h" or "\e[?1002h") and the extended
encoding ("\e[?1005h").

It would be nice, if the patch could find its way into emacs.

Thanks,
Olaf
