Where I was coming from is that this is a pretty minor cosmetic issue;
and while it makes sense for gdb to follow this rule, it isn't worth it
for 3rd party commands.  So, we should test gdb itself to avoid problems
here, but ignore problems coming from elsewhere.

I don't feel super strongly about it.
