Simplify layout, and make it more consistent with that of the other
man pages. Also I cannot see a good reason for keeping split the two
sections.

All these parameters contain a list of values, using plural names for
them help understanding a little.

Allow these functions to convey the reason of the failure to the
calling function, failure which is not always due to a parsing error
but it may depend for example on a memory problem.

Also fix several potential memleaks.
