Fails to format certain macro calls after encountering one with invalid syntax

[topecongiro]

If rustfmt encounters a macro call with invalid syntax, it fails to format some macro calls that comes after.

E.g., in the following code snippet,

foo!(|x = y|);

f!(match a {
    _ => (  ),
});

g!( 1, 2, 3 );

the argument of foo! is not valid syntax of rust. It fails to format f! that comes after, but successfully formats g!.

Interestingly, if g! comes before f!, then rustfmt is able to format both f! and g!.

foo!(|x = y|);

g!( 1, 2, 3 );

f!(match a {
    _ => (  ),
});

This is partially fixed on master (99edc88). That is, the first code snippet formats to

foo!(|x = y|);

f!(match a {
    _ => (  ),
});

g!(1, 2, 3);

The ( ) in the f call is still unformatted

I believe the original issue was fixed as rustfmt doesn't stop formatting after encountering a macro with invalid syntax.
