I went with isatty(1) in the suggested minimal bugfix[1] since I think
it is safe to assume that no one that doesn't have stdout connected to
a terminal should even care if the invoking editor dies and messes
with their terminal, and hopefully whoever is hacking git commands
that invoke an editor to read its output, is actually not doing it
through a tty but a pipe.

What problems do you foresee with isatty?, the current code already
checks for errors on accessing the console, but as Phillip
suggested[2] in that thread a signal might be generated for some of
those errors when the terminal is shared with other processes.
