Seems the ABI changed in 2009 here, Jan 30 2009 version only has the _
<non-negative number> part there, while Feb 25 2010 already has the current
wording.  I found:

Changing write_discriminator is trivial, but I guess we need to handle it
differently based on -fabi-version=.  Not sure what to do in the demangler, if
the <discriminator> is followed by something that starts with a number, it will
be hard to properly demangle it if we want to support old and new ABI
demangling.
