This bug still happens, even with the new Emacs GDB/MI interface. But I wonder
if it is interesting to tackle this issue from inside GDB, who, IMO, should be
agnostic as to which environment it is running.

What I do in gdbhelpers (https://github.com/tromey/gdb-helpers)
is detect when running in Emacs and then set an environment
variable inside gdb:

os.environ["EDITOR"] = "emacsclient -n"

However this relies on the Emacs user invoking (server-start).

Doing anything fancier would need a change to MI and a corresponding
change to Emacs. Not impossible but the above was a lot simpler.
