I forgot to mention it, but the above was done also to make it
"possible but not mandatory" to pay extra allocation penalty.  The
caller can choose to parse the string into an int, for example,
without extra allocation.  Only the ones that want a string value
and keep a copy around do have to do xmemdupz().

In the longer term, I think giving callers access to the parameter
value given to a capability is necessary.  If we had this facility
in the old days, we wouldn't have done side-band-64k but spelled it
as side-band=64k.

For the agent=<foo>, certainly we don't need it.
