Backwards compatibility with the output of older releases I
think. It
certainly goes back to 99.2 when tagged output for 'p4
clients', 'p4 labels'
and 'p4 branches' was introduced.

Yes, it's an unfortunate anachronism and easy to be caught
by. Unfortunately,
there are plenty of scripts out there that depend on it, so
changing it now
would break a lot of things for a lot of people.
Note that if you call 'FetchClient()', then the field is
called 'Client'. You
can see this yourself by running:
p4 -ztag clients
p4 -ztag client -o (with a 2005.2, or later, server)
Note that the same duality is present for labels and
branches too (i.e.
'label' vs. 'Label' etc.); also a vestige of the 99.2
tagged support for
these commands.
