commit '*: remove "Options:" string from help texts' broke build

[Cristian Ionescu-Idbohrn]

Left macro USAGE_PS undefined.

Error message:

	In file included from applets/usage.c:30:0:
	include/applets.h:351:1: error: expected '}' before 'USAGE_PS'

This (possibly not most optimal) patch:

diff --git a/procps/ps.c b/procps/ps.c
index 213695f..279f25e 100644
--- a/procps/ps.c
+++ b/procps/ps.c

 //usage:#define USAGE_PS "\nThis version of ps accepts no options"
 //usage:#else

 //usage:
 //usage:#define ps_trivial_usage

makes it build again.


Cheers,
