74b1745a19 Fix compiler error on some GHC versions 
Fixes the following error:

    src/ShellCheck/CFGAnalysis.hs:1394:40: error:
	* Couldn't match expected type `[S.Set a]'
		      with actual type `M.Map String FunctionValue'
	* In the second argument of `($)', namely
	    `mapStorage $ sFunctionTargets state'
	  In the expression: S.unions $ mapStorage $ sFunctionTargets state
	  In an equation for `declaredFuncs':
	      declaredFuncs = S.unions $ mapStorage $ sFunctionTargets state
	* Relevant bindings include
	    declaredFuncs :: S.Set a
	      (bound at src/ShellCheck/CFGAnalysis.hs:1394:13)

128351f5ef Permit colon after exec 
ShellCheck throws warning SC2093 when a script contains commands that could never be executed because they are after an `exec`.  Command `:` does nothing, so add it to the list of commands that don’t trigger this warning.
