The %end tag causes errors

[whitivery]

In a CentOS 5.5 kickstart file, adding %end to mark the end of the
%packages, %pre, or %post sections causes an error.  In the first two
cases the kickstart fails and stops.  For the %post it gives an error
message but it has already run all of my post steps so it doesn't have a
functional impact.

Without the %end lines, the kickstart file works fine.

Details:

- %end on %packages: traceback starts with:
    File "/usr/bin/anaconda", line 733, in ?
  and near end says KickstartParseError
  and identifies a kickstart line (which doesn't correspond
  to a %end)

- %end on %pre: traceback starts with:
    File "/usr/bin/anaconda", line 900, in ?

- %end on %post: my steps work but at end:
  {temporary ks filename}: line 490: fg: no job control


I don't see anaconda identify its version, but the RPM included
with CentOS 5.5 is anaconda-11.1.2.209-1.el5.
