Hey, thanks for the patch.
Next time, please make sure to send patches to
gdb-patches@sourceware.org. Also I don't see you on gdb/MAINTAINERS, do
you have copyright assignment for GDB? This patch is simple enough to
go in without a copyright assignment, but if you intend to send more
patches please let me know (in off) and I can get you started on the
process.

^^^^^^^^
You're using spaces instead of a TAB here.

I am not sure what others think, but instead of depending on bash (which
may not be available on all platforms), I'd rather rewrite those
commands to avoid brace expansions at all, thus making them compatible
with sh. I am not a maintainer however, so you'd better wait for one
until you do that.
Thanks,
