Yes, this is a separate issue; let's leave the behaviour as is for now.

This is OK.

I think you should get Write After Approval access to the GDB CVS so that you
can commit your approved patches yourself.  Please apply using this form:
http://sourceware.org/cgi-bin/pdw/ps_form.cgi

Once you get access, please add yourself to the MAINTAINERS file under
the Write After Approval section, and then commit your patch.

Bye,
Ulrich
