FileChooserDialog class>>openOn: works quite nicely, but the example given
in the class comment leads to message not understood #opneOn:pattern:message:

Can we get the class comment updated with the right expected usage? A class
comment for DirectoryChooserDialog would be good too.

I do like the actual file chooser/saver dialogs, they work nicely and are
easy to use.

I have a questionabout FileAbstractSelectionDialog>>suffixList:. Not all
operating systems and file systems make use of the unixy 'name.suffix'
convention.  For example OpenVMS uses [Directory]FileName.Extension;Version
where the trailing file version number would not fit nicely. I realize that
nobody is using VMS for Squeak at the moment, so this is just an example.
My question is, would it be better to use the actual match patterns (such
as '*.txt') rather trying to construct the match pattern in suffixList: ?
