Most probably, because this is what I have in my bzr branches.  I
guess that's because of umask, see below.

Stock GDB does not reject such a .gdbinit.  That was the gist of what
I was saying.

It was sufficiently controversial at the time to not make it into the
official GDB.

I do, FWIW.  Don't ask me why, it's something I have in my .bash_login
since about forever.

No Emacs changes are needed in any case, since RMS can chmod the file,
and bzr will not touch the write mode bits.
