util.argparse: Return final 'arg' table with positional arguments for convenience This is the same as the input table (which is mutated during processing), but if that table was created on the fly, such as by packing `...` it's convenient if it also gets returned from the parse function.

# How to:
# First, `make yourhost.cnf` which creates a openssl config file.
# Then edit this file and fill in the details you want it to have,
# and add or change hosts and components it should cover.
# Then `make yourhost.key` to create your private key, you can
# include keysize=number to change the size of the key.
# Then you can either `make yourhost.csr` to generate a certificate
# signing request that you can submit to a CA, or `make yourhost.crt`
# to generate a self signed certificate.

.PRECIOUS: %.cnf %.key

# To request a cert
