[bug-recutils] Support for the set-add operation in recset

[Jose E. Marchesi]

Hi.

recset now supports the -S operation, that sets the value of a named
field if it exists in the matching records.  In case a field with the
given name is not found, it is added to the record.

So, given the following record:

Id: 100
Summary: This is task 100
ClosedAt: Mon Jan 17 12:30:23 CET 2011

If we execute

recset -e "Id = '100'" -f ClosedAt -S `date`

the record will change to:

Id: 100
Summary: This is task 100
ClosedAt: Fri Jan 21 20:48:54 CET 2011

It has the same effect than -s in this case.  But if the record does not
contain a field named ClosedAt, -S will add it.
