Neat.

Most TEST_ environment variables that git respects are under
GIT_TEST_* --- e.g., GIT_TEST_OPTS. Should this match that pattern
as well, for easier debugging with commands like 'env | grep GIT_'?
What happens if the child in turn calls git again? Should this
unset TEST_GDB_GIT in gdb's environment?
The gdb manual and --help output advertise "--args". Has "-args"
(with a single dash) always worked?

Does the 'exec' after the fi need this as well? exec is supposed to
itself print a message and exit when it runs into an error. Would
including an 'else' with the if make the control flow clearer? E.g.
if test -n "$TEST_GDB_GIT"
then
exec gdb --args "${GIT_EXEC_PATH}/@@PROG@@" "$@"
else
exec "${GIT_EXEC_PATH}/@@PROG@@" "$@"
fi
Thanks,
