completion of filenames

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

As I have it now TAB only completes filenames after some leading 
command.  If I hit TAB at the beginning of a line it seems to want to 
find commands.  Can I have filename completion active right from the 
start?  Reason being that if I have a suffix alias defined then of 
course all I need is the filename.  I'm terrified to play with it since 
one can break something and only find out latter that expansion no 
longer works in months beginning with 'A'  or some other disaster.  Man, 
such power there, if only there was some way for mortals to understand it.
