[pass] [patch] use getopt to regularize options

[Jason A. Donenfeld]

It looks like Homebrew has:

    https://github.com/mxcl/homebrew/blob/master/Library/Formula/gnu-getopt.rb

Would someone investigate this, and tell me how it works? Does it
install it into /usr/local/bin, and is /usr/local/bin, by default
higher  in PATH than /usr/bin? Or does it install it as gnu_getopt,
and so I need to change the names of functions? Or what? What's its
invocation?

Running out the door now, but I'll look into it later.
