[nongnu] elpa/go-mode 7ab928a 146/495: Add support for methods that have no name for the receiver

[ELPA Syncer]

branch: elpa/go-mode
commit 7ab928a57e4d6b8b16b27faabc848beb180e5246
Author: Dominik Honnef <dominikh@fork-bomb.org>
Commit: Dominik Honnef <dominikh@fork-bomb.org>

    Add support for methods that have no name for the receiver
    
    `func (Foo) ...` is valid Go. Our regexes didn't catch this as method
    definitions and in turn broke fontification as well as navigation (and
    thus also indentation) for those.
