Why is my GDB batch mode exit status always 0?

The GDB docs say:

-batch

Run in batch mode. Exit with status 0 after processing all the command files specified with ‘-x’ ... Exit with nonzero status if an error occurs in executing the gdb commands in the command files.

But even when there are errors, I get an exit status of zero. For example:

$ cat gdbscript 
foo
$ gdb -batch -x gdbscript 
gdbscript:1: Error in sourced command file:
Undefined command: "foo".  Try "help".
$ echo $?
0

The GDB program status is correct if I use quit 1, for example, in the script.

Why is this happening to me? Is there a way around it? I'm trying to flash a remote target, and I'd really like GDB to exit with error status if it fails.

My GDB version, should it happen to be important:

GNU gdb (GNU Tools for ARM Embedded Processors) 7.8.0.20150604-cvs

It is known gdb Bug 13000. You can apply experimental patch from Bug 13000 and rebuild gdb which may work for you.
