Hello,

debbugs-gnu.el binds debbugs-gnu-select-report and
debbugs-gnu-select-usertag to [return].  Unless I'm mistaken, this
designates only the function key, and terminals do not tell applications
that function keys were pressed.  In the case of [return], they only
send RET, i.e. the C-m character.

Concretely, this means that on a TTY, the return key is not bound to
those functions, as RET is bound to newline.  Pressing return thus leads
to the following error message:

> command-execute: Buffer is read-only: #<buffer *Emacs Bugs*>

(Also, weirdos like me who actually use control+m instead of the return
key are screwed on graphical sessions too.)

On the other hand, if one binds those functions to (kbd "RET") ≡ "\C-m"
≡ "\r", Emacs automatically translates [return] to RET, and everything
Just Works™.
