patch: enable transient mark mode

[Jarek Czekalski <jarekczek@xxxxxxxxxxx>]

I found this issue already reported in 2009:
https://www.emacspeak.org/VCCS-archive/2009/msg00000.html

It is very difficult for me to live without transient mark mode. This 
patch seems to fix the problem.

Before this patch some commands (for example dtk-speak) caused 
deactivation of the mark. Even right after setting the mark with C-SPC 
and checking by evaluation of mark-active, the result was nil. Now I see 
transient-mark-mode works in simple cases. If one finds a case where it 
still has problems, please report.
