delete-char vs "mouse-region" and "transient-mark-region"

delete-char vs "mouse-region" and "transient-mark-region"

[Mathias Dahl]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

1. $ emacs -q

2. Create two lines of text:

line1
line2

3. Mark the first one using the mouse and press C-d (delete-char). The
   marked region will be deleted.

4. Mark the second line using transient mark mode (C-SPC C-CPC C-e)
   and press C-d. The region will not be deleted.

Is it just me or would others also like to have both these marked
regions behave in the same way?

If the decision is to delete the region in both cases, may I suggest
that DEL (<backspace>) also deletes marked text?
