Peter Wemm c46d792d58 Deal with quoted arguments. This hack parser uses whitespace to delimit
fields, not lex/yacc grammar so it is not an exact match but should be
close enough for most cases.
Deal with 'port?', 'irq?' style specifications.  These are parsed as
seperate values in lex/yacc in config(8) but tripped up this helper tool.

# This is a transition aid. It extracts old-style configuration information
# from a config file and writes an equivalent device.hints file to stdout.
# You can use that with loader(8) or statically compile it in with the
# 'hints' directive. See how GENERIC and GENERIC.hints fit together for
# a static example. You should use loader(8) if at all possible.
