flyspell and mouse selection / transient-mark-mode

[Reiner Steib]

Recently there a strange interaction between flyspell mode and
selecting test with the mouse or using transient-mark-mode:

(0)  Create this file:
     echo "# This is a Makefile foo bar" > Makefile

     (The problem is not specific to GNUmakefile mode; I also see it
     in other modes, e.g. message mode.)

Case (A): [flyspell / mouse]

(A1) Start Emacs:
     emacs-cvs -Q Makefile -f toggle-debug-on-error -f flyspell-mode

(A2) Mark the word "Makefile" with the mouse.

(A3) Hit `C-w'

(A4)  I get the following debug output and the word "Makefile" is *not*
     killed:

     ,----
     | Debugger entered--Lisp error: (mark-inactive)
     |   call-interactively(kill-region)
     `----


Case (B): [flyspell / transient-mark-mode]

The same failure occurs here:

(B1) emacs-cvs -Q Makefile -f toggle-debug-on-error -f flyspell-mode \
       -f transient-mark-mode

(B2) Set mark using C-SPC on the start of the word "Makefile" and move
     point to the end of the word.

     (Additionally, the region is not highlighted as I'd expect with
     transient-mark-mode)

(B3) Hit `C-w'

(B4): The same error as in (A4).


Case (C): [flyspell mode off / mouse]

(C1) emacs-cvs -Q Makefile -f toggle-debug-on-error -f transient-mark-mode

(C2) and (C3): See (A2) and (A3)

(C4) No error.  I get "# This is a  foo bar" as expected.


Case (D):  [flyspell mode off / transient-mark-mode]

(D1) emacs-cvs -Q Makefile -f toggle-debug-on-error -f transient-mark-mode

(D2) Set mark using C-SPC on the start of the word "Makefile" and move
     point to the end of the word.

(D4) No error.  I get "# This is a  foo bar" as expected.
