Comment 4 for bug 1023012

HFS doesn't permit a file to have a '.' character in the initial position.

This should be removed for the user attempting to save a file. I happen to know about OS9 drivers so it only took me 30 seconds to figure out why the 'Save' button wasn't lit up, but it's not terribly obvious for the typical user. It would be good to filter this (and any other illegal characters) for the user.
