I should probably rewrite the message as I did it in an awful hurry. ;)

The main point was getting across was that in the normal scheme of mangling
it follows the convention in a nutshell:

TypeStruct QualifiedSymbol (Int Symbol) ...

Eg:
S6foobar5inner...

Should 'foobar' be an extern (C) function, then the initial string count is
omitted.

Sfoobar5inner

Causing core.demangler to choke on it.

This affects the demangler I've written for gdb as it follows the same
rules to parse the mangled string.
