Well adding an unused feature does increase the long term maintainence
load - but if we agree this does seem useful, that's fine.

Also settling on the record/alignment count as the return value
prevents any future alternative.  But right now I can't think of any
other sensible return value.

I've written a patch against CVS to implement this - see Bug 2628 for details.
