commit 3fddb62913c72f29843335aa796c2e444ded1608
Author: Tim Baumann <tim at timbaumann.info>

    Fix: Generate pattern signatures for constructors exported as patterns (#663)
    
    * Fix pretty-printing of pattern signatures
    
    Pattern synonyms can have up to two contexts, both having a
    different semantic meaning: The first holds the constraints
    required to perform the matching, the second contains the
    constraints provided by a successful pattern match. When the
    first context is empty but the second is not it is necessary
    to render the first, empty context.
    
    * Generate pattern synonym signatures for ctors exported as patterns
    
    This fixes #653.
    
    * Simplify extractPatternSyn
    
    It is not necessary to generate the simplest type signature since
    it will be simplified when pretty-printed.
    
    * Add changelog entries for PR #663
    
    * Fix extractPatternSyn error message
