For example: the argument of -c had a mistaken plural "s", the argument
of -o was misformatted, the main description spoke of "options" instead
of "parameters" and used a mistaken "i.e." instead of "e.g.", and so on.

Also, sort the options in the synopsis alphabetically, to make it easier
to find a specific one and to match the order in which they are listed
further down.  Also, remove some excess spaces, harmonize the style of
some decriptions, sort d, w, m in the order of ascending duration, and
for consistency use hyphens instead of underscores in option arguments.
