#378 ctags ignores C++ typedefs that use "using"

[Shachar Shemesh]

C++11 introduced defining typedefs using the "using" keyword as so:

using SomeType = uint8_t;

I've confirmed with the ctags bundled with Ubuntu 18.04:

Exuberant Ctags 5.9~svn20110310, Copyright (C) 1996-2009 Darren Hiebert
  Addresses: <dhiebert@users.sourceforge.net>, http://ctags.sourceforge.net
  Optional compiled features: +wildcards, +regex

I've also confirmed this with trunk, revision 816.

Universal-ctags (https://ctags.io), unofficial project forked from here can tag it well.

$ cat /tmp/foo.cc
using SomeType = uint8_t;
$ u-ctags -o - /tmp/foo.cc
SomeType    /tmp/foo.cc /^using SomeType = uint8_t;$/;" t   typeref:typename:uint8_t    file:
