Support for C++11 Trailing Return Type

[oosubhisara]

So Tagbar can recognize this new format

auto getSomeValue() -> int
{
    return  10;
}

Supporting new syntax like this is not up to tagbar per-se, the backend used needs to support it and give us some kind of a symbol marker for it. I'm not a C++ guy here so I'll be pretty dependent on you or somebody else reviewing this.

Can you check whether universal-ctags has support for this syntax? If not this needs to be reported upstream not here. It will be close to impossible to support if the tags generator doesn't report anything.

If it does, how is it labeling them in the output? It should be a pretty simple matter of adding the appropriate tag mapping, perhaps you could submit a PR that fixes this yourself.

u-ctags supports the syntax:

[jet@living]~/var/ctags% cat /tmp/foo.cc
auto getSomeValue() -> int
{
    return  10;
}

[jet@living]~/var/ctags% u-ctags -o - /tmp/foo.cc
getSomeValue	/tmp/foo.cc	/^auto getSomeValue() -> int$/;"	f	typeref:typename:int

[alerque]

@masatake We'd be happy to accept a PR that added first class support for mapping that ctags output to the existing tagbar layouts.
