Gnus/5.13 (Gnus v5.13) Emacs/24.0.50 (gnu/linux) |
1. emacs -Q
2. M-x ediff-regions-linewise, type RET twice to use *scratch* for both
Ediff buffers (it doesn't matter which buffers are used).
3. Try to select a region with the mouse
=> Emacs beeps and announces the error "mouse-drag-track: The mark is
not set now, so there is no region"
This happens on any click of the mouse in the buffer. Nevertheless, it
is possible to select a region by dragging the mouse with mouse-1
pressed. Subsequently, further mouse clicks do not raise an error any
more. The bug also happens if I visit a file and call
ediff-regions-linewise on it.
If I comment out the line
(ediff-activate-mark)
in ediff-clone-buffer-for-region-comparison (in ediff-util.el), then
eval that function, visit a file and call ediff-regions-linewise, then
clicking with mouse-1 does not raise an error.
I observe this bug since r101737, which fixed bug#7044. That bug
prevented even trying step 3 in the above recipe, so I don't know if the
fix introduced the mouse-drag-track bug or revealed it.
