[nongnu] elpa/go-mode 35a5ddc 445/495: indent: fix decl statements with dangling "="

[ELPA Syncer]

branch: elpa/go-mode
commit 35a5ddc1299371ea0f8f050800944e1c35806cfc
Author: Muir Manders <muir@mnd.rs>
Commit: Peter Sanford <psanford@sanford.io>

    indent: fix decl statements with dangling "="
    
    In "var", "const" and "type" statements, a dangling "=" does not
    indent the following lines. We now test for this case and don't treat
    the "=" as a dangling operator.
    
    var foo =
    // don't indent me
    123
    
    Note that the above is a syntax error without the comment.
