Use global substitution for %c and %p

I use complex command to run specs like this:
    
    if [ -e .zeus.sock ]; then zeus rspec -f documentation --color %p; else bundle exec rspec -f documentation --color %p; fi;

It checks if zeus is running, and if yes, runs spec using zeus, or using rspec otherwise. Here I have %p macro twice, that's why I need global substitution. 

Please, merge it if you find it can be useful, or just close this request. Thanks.
