commit c25168bd9a4fd5d0acb8c83cad07d56c36cd8f6f
Author: Alan Zimmerman <alan.zimm at gmail.com>

ApiAnnotations : PatBind gives wrong SrcSpan for the pattern.
Summary:
The production for decl_no_th starts
decl_no_th :: { Located (OrdList (LHsDecl RdrName)) }
: sigdecl { $1 }
| '!' aexp rhs {% do { let { e = sLL $1 $> (SectionR (sL1 $1 (HsVar bang_RDR)) $2) };
pat <- checkPattern empty e;
...
The e value should be just the pattern, excluding the rhs, but the span
created includes the rhs.
