Remove arrays in usage text, use a single string instead

Currently, usage is an array of pointers to string.
It is meant to support this:

usage: foo --bar
   or: foo --baz
   or: foo -z

The patch removes this and makes usage just a string:

usage: foo --bar

Why remove this?

(1) We can achieve old format by using the usage string with many lines:
usage = "foo --bar\n"
"   or: foo --baz\n"
"   or: foo -z";

(2) We don't use multi-line usage anyway.
