You seem to be using the chapter/section names in the parentheses.
You should be using node names instead (or use Emacs, which will do
that for you ;-).

Please don't remove the version information from this text.  At the
very least, we should tell what GDB version introduced the latest mi3
syntax.  We should tell this here, and not only in the "Interpreters"
node, because this section is a concise list of invocation options,
and should include the important information without sending the
reader to read the more detailed parts.

GDB 9.1, presumably?

I think the old text is better.

Thanks.

P.S. I wonder how did we let this problem slip through the cracks when
multiple-location breakpoints were introduced?  Maybe we should do
something to avoid such mistakes in the future.  We really shouldn't
be changing the MI syntax in incompatible ways so late into GDB
development cycle.
