Okay, when I was viewing the `svn diff`, I was wondering what it was
for - but that makes sense.

Tests needed! :)

Also, regarding this snippet...

    # if the default value has been changed after FormFu->process has been
    # called we respect the change here
    if (    $submitted
         && $self->force_default
         && defined $default
         && $new ne $default ) {
        $new = $default;
    }

The comment contradicts the code.
It says "respect the change", but you're actually overwriting the change.
Would a more suitable comment just be...
# overwrite any changes
?

Ok, but try to keep formatting changes to a separate commit, so if
anything needs rolled back, it's easier.

Anyway, that was perltidy's formatting, so your change will get lost
the next time I run perltidy on all the files.
To help with consistency, I've added my ".perltidyrc" file into the
trunk/HTML-FormFu directory, so if anyone else runs perltidy within
that folder, it'll use the same settings

If anyone's interested, the commands I use to run perltidy on all .pm
files in "lib" and all .t files in "t" are:

    $ find lib -name '*.pm' -exec perltidy -b '{}' \;
    $ find t -name '*.t' -exec perltidy -b '{}' \;

And to remove the backup files it creates:

    $ find lib -name '*.bak' -exec rm -f '{}' \;
    $ find t -name '*.bak' -exec rm -f '{}' \;

Cheers,
Carl
