complex numbers in library function (PR#1737)

[murdoch@stats.uwo.ca]

This looks like bug  PR#1697 in the deparser.  I've written a patch
that fixes that case; I'll check out this one.

The difference is that in the first case R keeps the source of the
function (in attr(phihat,'source')).  In the second case it deparses
the internal representation.
