[Ur] about the UrFlow Demos

[Fabrice Leal]

Hi, I downloaded the scdv.tgz and tried to compile the demos but had to fix
a "wrap" function used throughout the poll, calendar, gradebook and forum
demos:
it seems that just replacing the arguments title and body with "titl" and
"bod" gets rid of the compilation errors, and then I seem to be able to run
the demos normally.

However when i run urweb with the -iflow switch, I get a few "Information
flow checker can't parse SQL query" notices, so I'm not sure if I'm missing
something or if there's anything needing fixing.

Thanks in advance :)
