This isn't an improvement: it's made it incorrect. The null string is
not necessarily empty, it is only empty by default. People keep making
this mistake (and indeed, the original patch made the same mistake in
its code, which I corrected), probably because specifyng anything other
than the empty string is unusual. However, snice we have made provision
for it not to be empty we should describe it accurately.

cheers
