Add an example for filepath tab completion

[krasi-georgiev]

Would you consider adding an example for a prompt that auto completed file names on tab presses?

I would consider adding such an example if it is small and to the point. My main concern is that proper filesystem access often requires much error checking, which might make the example more about the filesystem access and less about liner.

Could you share some code here as a starting point and I will use it to see if it turns out to be working well or not

[peterh]

Sorry, I misunderstood. I thought you offering to write an example for others.

[krasi-georgiev]

yeah I thought this is a common feature so was hoping someone already wrote it.
