Cygwin lack of 'o' option for ps shows error messages on every prompt

Browse Source 
Cygwin doesn't support the 'o' option for ps (version: ps (cygwin) 1.7.17), which causes errors to show on every prompt
displayed. A simple fix is redirecting stderr to /dev/nullin liquidprompt/liquidprompt (it might actually be a good idea
to do the same for other commands, since any kind of undesired output makes the prompt pretty much blow up).
