[Omake] short-circuit returns

[Nathaniel Gray]

Ok, maybe I should just give you some actual code that triggers the  
problem.  My goal is to find a description of why a build failed and  
send it to growlnotify.  This is in my ~/.omakerc:

section
     .BUILD_BEGIN:
         echo
         echo "Build beginning" | growlnotify -n OMake OMake

     .BUILD_SUCCESS:
         echo "Build succeeded!" | growlnotify -p -2 -n OMake OMake

     .BUILD_FAILURE:
         section
             targs = $(find-build-targets Failed)
             any-output-file(targs) =
                 foreach(x, $(targs))
                     if $(x.output-file)
                         return $(x.output-file)
                 return $(BUILD_SUMMARY)
             f = $(any-output-file $(targs))
             shell(cat $(f) | growlnotify -s -p 2 -n OMake OMake:  
Build Failed!)
