Possibility to make bindgen only generate a single extern block?

[faern]

Input C/C++ Header

void foo();
void bar();

Bindgen Invocation

$ bindgen input.h

Actual Results

extern "C" {
    pub fn foo();
}
extern "C" {
    pub fn bar();
}

Expected Results

It becomes very verbose for no reason that is apparent to me. Personally I would prefer the following output:

extern "C" {
    pub fn foo();
    pub fn bar();
}

Maybe there is already a way to do this, but I could not find it. Nor did I find any issue touching the issue.

Closing as a dupe of #564.

TL;DR: Patches welcome as long as they're not a burden to maintain, but... I can't think of a nice way to do this that doesn't include adding yet another intermediate representation, or processing phase.
